My Neural Network can recognise handwritten digits!!!
It's my second try at NN so it's faaaar from perfect (or maybe even good), but hey, it's something and only with High schools, I'm pretty satisfied with the results. If you've not seen my previous post, I'm just trying to learn NNs in C and am doing just really basic things.
Still I'm proud of my progress!
Now I'm looking forward learning some library (OpenNN + OpenCV seems cool) and trying more advanced stuff, wish me luck 😆14 -
This is why one shouldn't code in more than one language a day. Basically spent almost 15 minutes to find out why it wasn't working.10

I have 2 screens @ my desk with my back facing manager's room. Whenever he opens his door, he can see my second screen.
Thinking of a side project based on webcam that will auto open visual studio upon seeing him. Any leads would be appreciated. 😊15 -
There is no planet in this multiverse where chrome should be using more ram than an ENTIRE VIRTUAL MACHINE. WHILE ITS COMPILING OPENCV!!! Seriously!?!?9

I'm using C++ for machine learning purposes using TensorFlow and OpenCV (rip Python, you are too slow 😭)
What are you using C++ for? 😁19 -
Dev Badass Rant
There are two occasions really:
1) For our C++ project in the third semester, we had to build any kind of C++ application. Guys in team of 4-5 built record keeping systems and calculators and one even made a Tic-Tack-Toe app. My friend and I, just the two of us, made a simple program that plays Rock Paper Scissors with you. With the power od OpenCV, it used the camera to track your hand movement, predicts your next move using contours, and displays the winning move as the computer's move.
For example, if you play Rock, the computer would predict that you were gonna play rock and display paper as it's move. It wasn't perfect, but it was ours, right from scratch. When it worked at the presentation, I was swell with pride. 😂
2) I was interested in game dev so I started Unity. The first tutorial in Unity you find is the web series by Unity about rolling a ball. You simply make a platform and control the ball with your keyboard and the camera follows your ball. You also make pick ups and get points based on that. So I started there, finished the tutorial, added a few walls, made edible and non edible pick ups, dimmed the entire scene, adjusted the camera angles, transferred controls to mobile gyroscope and added a few other things and voila! MazeBall was born. It has only one level and I thought it was pretty shit.
I decided to show it to a friend and when I showed it to my mate (the one who I worked with in the C++ project), my other classmates saw it and were impressed. Like so impressed a couple of them transferred it to their phone and took home with them. 😂 Was inspired to improve.4 -
Today I met a random guy who contacted me through Facebook to teach him some C++.
He wanted to create a small anomalies detection system on x-ray images with OpenCV (for industry purposes).
The guy came from Nigeria, where he studied medicine, but here has to work on two completely unrelated minijobs to survive.
And he still finds energy to keep learning new crazy stuff like C++ (he definitely chose the hard path to learn some programming).
And that's it, there's no moral for this fable, just a short story. Learn whatever you want from it.2 -
Made this project "Come Fix Me" in a 24hr hackathon. Won the most innovative solution.
An android application for citizens(users) which allows them to register issues on potholes in their area.
Web for report management
Usage Flow:
User clicks a photo of the pothole and registers a new issue.
The photo gets uploaded on the firebase database along with other information like GPS co-ordinates.
The image is downloaded in the server and served in the pothole detection script.
If pothole is detected an estimated area is calculated, if no pothole is detected user's issue gets rejected.
After successful detection details are uploaded on the web for administrator, these issue are forwarded to govt. officials.
Once the officials claim that they have fixed the pothole, the user gets a notification and they can close their issue if pothole is fixed

Continuation from :
https://devrant.io/rants/835693/...
Hi everybody! I am sorry that as a first time poster I am building 2 long stories, but I really like the idea of connecting with other people here!
Well, as I was mentioning before, I got a job in Android development and had a blast with it. Me and the developer clicked and would spend our time discussing PHP, the move to other stacks (I was making him love the idea of Django or Spring Java) games, bands and cool stuff like that. This dude was my hero, his own stack was developed in a similar MVC fashion that he had implemented from scratch before for many projects. It was through him that I learned how to use my own code (rather than frameworks and other libraries) to build what I wanted. I seriously thought that I had it made with a position that respected me and placed me in the lead mobile development position of the company. Then it happened. He had taken 2 weeks of unauthorized leave, which was ok since he was best friends with the owner of the company, those 2 along another asshole started it so they could do whatever they wanted. And I could not make much progress without him being there since there were things that he needed to do, that I was not allowed, for me to continue. When he came back I was quickly rushed to the owner of the company's office to discuss my lack of progress. The lead developer was livid, as if he knew that he had fucked up. He blamed the whole thing on me (literally told the owner that it was my fault before I was summoned) and that we lost 2 weeks of business time because I did not had the initiative to make progress on my own. I felt absolutely horrible, someone that I had trusted and befriended doing something like that, I really felt like shit. I had mad respect and love for this guy. It got heated, I showed the owner the text messages in which I showed him my pleas to led me finish the parts that were needed while he was away. Funny enough, he acted betrayed. After that it was 3 months of barely talking to one another except for work related stuff. He got cold and would barely let me touch the internal code that he was developing. It was painful. The owner kept complaining about progress and demanded that I do a document scanner for the company, which was to be attached to their mobile application. Not only that but it had to be done with OpenCV. Now, CV is great, but it is its own area, it takes a while to be able to develop something nice with it that is efficient and not a shitstorm.
I had two weeks.
Finished in one. After burning my brain and ensuring that the c++ code was not giving issues and the project was steady I turned it in...to their dismay. And I say so because I felt that they gave me such a huge project with the intention of firing me if it was not done. After that it was constant shit from the owner and the lead developer. I was asked then to port the code to the IOS version. I had some knowledge of it already so I started working on it. Progress was fast since the initial idea was already there and I really love working on Apple devices. And when I was 70% done the owner decided to cut me loose. At first he cited things such as lack of funding and him being unable to pay my salary. I was fine with that even though I knew it was not true. So at the time I just nodded and thanked the company for my time there. Before I left, he decided to blame it on me, stating that if they were not producing money that it was perhaps my fault. I lost my shit, and started using my military voice to explain to him how a software company is normally ran. Then I stormed out.
It was known to me, that the lead developer had actually argued against me being laid off. And that he was upset about it, we made amends, but the fact remains that I was laid off because the owner did not think of me as an asset, regardless of how many times I worked alongside the lead developer or how valuable I was actually to the company, their infrastructure did get better while we worked together, so I just assumed that he never actually did any mention of my value.
I lasted 2 months without a job, feeling horribly shitty because my wife had to work harder to ensure our stability whilst I was without any sort of salary. At this time I had already my degree, so all I had to do was look better. In the meantime I decided to study more about other technologies. I learn React, and got way better at JS and Node that I thought I could and was finally able to get another job as a full stack developer for another company.
I have been here since 2 months. It has been weird, we do classic ASP, which is completely pointless at this time, but meh. At this time though, I just don't really have the same motivation. Its really hard for me to trust the people that I work with and would like to connect with more developers.21 -

MY OPENCV SIDEPROJECT WORKS!!
Now I can chill in bed and control the computer with a laser pointer :)8 -
Lots of fun open source stuff, but I had a lot of fun working on a survey taking m&m dispenser. The goal was to encourage students to answer survey questions that would help the faculty get a better idea of what the students found most valuable (different things they wanted to learn, classes they found useless, etc.). So me and another student built this :) Its a node server running on an Intel Galileo, which served up an admin and survey interface using React. When a student answered a survey question, a servo would turn a gear, which interfaced with a rack and pinion that had two little pits in it. When it would slide under the jar, two m&ms would fill the pits, then the rack and pinion would push them out. Then we had a webcam hooked up to the end of it that would compare the colors of the m&ms to see if they were the same. If they were the same, the student would get more m&ms. The gear pieces were 3D printed.
We could never get the webcam stuff to work right with the Galileo because OpenCV (the computer vision library we were using to interact with the webcam) could not be built/compiled on such a specific version of Linux. Later, I was able to do it with a RaspberryPi, but never got it reintegrated.5 -
I might be fucked up, but I have a tendency to gravitate towards the shit that everyone else dislikes for the sake of knowing if their bias against is actually because shit is truly fucked up or if shit is legit plain WRONG.
From all technologies that I have worked with professionally I can count:
Java(currently in the form of old JSP services for an "enterprise level application")
Java for Android development - i was the lead engineer for a mobile project
Swift with IOS dev, same gig as the above.
C++ for Android development in the form of OpenCV with Java as well.
Javascript in all possible forms, basic input validation, ajax services, jquery datatables, jquery animations and builders.
Css/sass heavily
Clojure for an ldap active directory application
Python for glue scripts
Classic ASP with JScript and VBScript
VB Net forms
C# For ASP.NET MVC
Bootstrap for multiple intranet frontends
Node+Express for a logistics warehouse management tool
Ruby on Rails freelancing small gigs
Php in all ways possible from complete standalone php apps to Laravel and just php+composer apps aaaaall the way to wordpress
Django consulting
I have found that the one that I dislike the most is wordpress. And the one that I like working with the most is Node. Don't know why, i just do really fucking like messing around with Javascript, the language has changed a fuckload throughout the years and continues to increase and change. It was my first scripting language following a stint in me trying to learn cpp way when i was starting and royally FAILING
Never really got the hate for it, even when I used JScript with classic ASP i just enjoy working with Javascript a lil too much. And from all the above mentioned stacks safe from Php is the one, or one of the ones in which i don't royally suck :V3 -
Currently trying to convert a Python (2.7) framework into its C++. Surprise, surprise, the C++ APIs are also all deprecated
"Here's a guide to creating your project using our non-deprecated framework, except it will still call our deprecated methods under the hood"
Additionally, I had to make this framework work with OpenCV, which was complaining about my C++ framework being deprecated and not being able to link to missing modules (which were already installed).
All of this has eaten 4 hours of my life, I could as well throw the laptop out of the window
"Try reinstalling the missing modules separately"
*installation takes less than 1 minute*
*runs build again, everything work*
I'm done for today *flies away in desperation* -
If you ever get an idea for an OpenCV project: shoot yourself in the foot, drink some bleach, do whatever it takes to get it out of your head, because it will all be less painful than the python docs for cv2.3

So my company was building a software to allow users to use a screen without the screen being touch itself.
It was made using a camera above the screen and then with openCV detect where the hand was.
Anyway I had to test it on the place.
And the place was a factory where they did produce pipes.
It's the biggest company in my city, and yet I was there, in the break room, coding a raspberry in winter in a factory.
The only source of heat was the fire used to melt the metal
That was literally awesome2 -
I was learning OpenCV and decided to build something practical and open source (for portfolio). I mixed computer vision and screen snipping tool, now I think what else to add.. any ideas are appreciated.

Before I was unceremoniously laid off by a shit company in which they tried to blame shit on me I was working on a opencv implementation of a proprietary document scanner.
I finished the Android prototype and was working on the ios implementation. It was left unfinished in the ios version because I was building it in swift and obj c to compare code bases.
They launched a shit unfinished Android app of their product without the scanner (they could not add the scanner lels) and have not been able to do shit on the ios version.
I did not give them the Android prototype. There was no binding contract that specified that what I developed was theirs. There is no record of anything.
The scanner? Is still in my phone and I still have the built project in my mac.
Unless them cheap assholes decide to pay another engineer for the opencv implementation, their vbscript php non theory knowing shit lead will have to figure out the required mat obj c swift java cpp code needed to build it.

I have that desire (which is with me since I was kid) to build a drone (Quad-copter) and control it with my hand gestures.
So, I decided to start with it in my spare time, I am planning to buy a Raspberry PI and other materials to build the drone, and create a Gesture Recognizer app using OpenCV.
Wish me some luck !6 -
Learning neural network algorithms and feeling very accomplished........
.......then checks out OpenCV and flips desk.4 -
About to kiss my love in my dream (feelings intensify) but suddenly the terminal with ImportError : No module named 'cv2' pops on her face. (Even worse than rejection)1

I learnt something from every single project I made, but this one... it was really different, new language, new library, new hardware.
Problem:
there's an infopoint in a place, that was really hard to use (ball mouse over a monitor)
Solution:
make the screen be touch.
Developing the solution:
- after a bit of research I find out there's a library/project called OpenCV
- there are example programs that detect hands written in C++ (which I know) and Python (which I don't know)
- the whole infopoint works on a raspberry PI, with raspbian (I'm not new to linux, but it's somehow different, plus tons of customization)
So I spend like 3 weeks trying to understand how to make it work, at first, the webcam was on the TV and you could move the mouse just by shaking your hand, but it didn't work too well, so we tried making the webcam look at the screen and then calculate the differences between "no-hands" and "user-hand", but should have been calibrated, wasn't too precise... dropped solution.
put the webcam 30cm above the screen, let it just analyse a few centimeters of sight from the screen and it worked flawlessly, BUT it could just recognise the horizontal axis => had to rework the infopoint UI to make it dumb-easy
It all finally worked, I learnt python, openCV, a bit of photography
Then hated it all and decided to never do that again -
On the university we made a robot using Lego, which communicated on bluetooth with a tablet. We wrote a smile detector using opencv for the tablet. On the tablet you saw the view of the front camera. And when you smiled into the camera, the tablet notified the Lego robot which gave you a chewgum. The purpose of this project was to demonstrate on a fair what our robotics group did. People really liked it. 🙂2
-
I just got a bit into OpenCV and I am completely exited. I built a little ball tracker (Yes I know that the cross is on the other side, it's inverted so the cross is at the same position as the ball in front of the camera) and although it is not the most advanced project I think it's kinda cool.9
-
Why do all the cool things have terrible documentation?
I'm looking at you Gnuradio and OpenCV!
Doxygen doesn't count if you don't actually write doc comments!!3 -
Fuck. I just want to fucking use OpenCV on CLion on Windows. Why the fuck do I need twenty fucking PhD's in quantum rocket science to set up a simple project with Cmake?
During the time I just wasted trying to get the correct library to link properly, I could have rewritten all of Tesla's fucking CV functionality from scratch, but instead here I am spending literal fucking hours googling why the fuck does 'recursive_mutex' not name a fucking type in namespace 'std' on mingw.
Fuck C++ I'm going back to C# where I can literally install OpenCV and all of its fucking dependencies from nuget with ***ONE*** fucking click.6 -
OpenCV is like an USB port: You never have the right input format and it only works after converting the damn thing multiple times!
-
Today has officially drained all the brain I didn't even have yesterday. Let's hope I get somewhere with this thing, or else all the brain I've wasted is going to be useless.
Also, fuck opencv's fisheye undistortion. Mofo, I don't have the camera params, how the fuck do you want me to give you your stupid kernel shit? Shut the fuck up from my face. Stupid hoebag.
... 😭😭😭😭😭 -
Learning Image Processing,Deep Learning,Machine Learning,Data modeling,mining and etc related to and also work on them are so much easier than installing requiremnts, packages and tools related to them!2
-
Gah I'm so mad at openCV right now. Is so stupid. Why the heck does it's kalman filter implementation accept 'float' as an acceptable type but not 'np.float32' gah gah gah it's so dumb spent half my day on that gah thank God for git diff it saved me cause it worked before and now gahhhhh. Anyway.

So I've finally implemented face detection in my discord bot.
@Wisecrack regarding the openCV training, I'm still taking positive and negative samples, so it'll be another while.
Also, why is post @ing not a thing5 -
back in college i started a project to manage my MTG and YuGiOh cards. I wanted to have a database for them with a graphical manager (already some older ones on github but i don't like the feel of them).
But between college work, the difficulty of building a SQL database schema for them and the fact I had hundreds of cards I'd need to put into the database manually I dropped the project after the 2 friends working with me also dropped out of the project.
But recently I found this hackster project (https://hackster.io/mportatoes/...), and i'm mostly sure I could retrofit it to use opencv to at least read the card title reliably allowing me to scrape the rest of the information from some wikia page as a new card is scanned. I'd just have to pick up a bin of legos at walmart lol
And previously learned about mongodb which would make storing the cards ina DB a lot easier than dealing with SQL.
I might pick this back up again, but when I first started I had 2 friends working on it with me who both dropped out before I finally gave up, so starting by myself might be a little demotivating. -
worst documentation.. OpenCV.
About half of the features I've used are not even mentioned in the documentation. The worst part is that at first look the website looks neat and well maintained but in reality it is missing a lot of usefull info. And some of it is plain jibberish.3 -
These moments I'm too dumb to even setup a library or anything. That's just so frustrating! I spent many hours realising OpenCV may not work on my machine6
-
I think instead of being lazy today and sleeping in until 3, I'm gonna spend my Sunday morning early afternoon learning something new or building something short and sweet. Not sure what I wanna go after though! I started getting into openCV but I'm not good enough quite yet for it to be somewhat enjoyable. I am a swiss army knife so I work a lot of stuff but I'm open to anything.6
-
Had to port a python code some other guy wrote using opencv for some image processing stuff to Java. I thought "how tough can it be? Let's just try it out on python first just to verify the results", only to waste an entire fucking day trying to install opencv first and make it work and to add to it the crappy opencv documentation were no help. In the end I had to just give up on this shit and decide to just do the Java implementation which I later verified from the python guy's results.

I have a system design question I was hoping u guys could help me with.
So I want to make a display that shows an animated wallpaper. I want to have a camera in the display that will recognize finger gestures and will change the wallpaper accordingly (shuffle to a new one, etc.)
EX: when the current wallpaper is displaying, when the user shows the camera the peace sign, it will switch the current wallpaper to a random wallpaper.
I used tensorflow and the mediapipe hands library to get the finger gesture recognition to work. I used tensorflow, python, and openCV.
Now that the finger gesture recognition is finished, I moved to the animated wallpapers and I made a couple with p5js.
How could I best combine the two? Should I switch from tensorflow in python to tensorflow.js? Or should I find a way to re-do my animated wallpapers in python?
My original plan was having the foundation of the whole system be python. This is so I can have the finger gesture recognition run on the main thread, and have another thread deal with the wallpapers.
Let me know if u guys have any ideas or if I’m not clear. Thanks!!!4 -
Hi the community!
Do you have any recommendation to start learning about artificial intelligence?
I would like to build a bot like http://uxchat.me/ but who also need more complex action, like image recognition with OpenCV maybe.
Any book, link will be appreciated2 -
Since 2 days I try to get opencv for python installed on my notebook but it doesn't work. On my desktop machine at work everything is fine but on my notebook it makes me cry - this sucks1

Hey guys I've a problem I've been trying to solve for a while. Also I'm a college student so my knowledge isn't going to be the greatest so go easy on me if it's simple to solve😂. So I'm creating a real time licence plate detector using yolo lite, my own deep learning ocr and plan to add the model to fast api. So as an input to the rest api, the user will submit a IP camera link for openCV to get individual frames for preprocessing before yolo predictions. The problem I have is how to I handle multiple real time IP camera feeds at once?. Ive been researching multi threading but read that it can cause issues with async definitions in fast api. Any advice will be greatly appreciated and if more information is needed just shout!.

Just wasted a day trying get Robot Operating System working.
Absolute rubbish software. Broken Gentoo Repos, Required packages that don't exist, failing to install cmake files to find the crap it installed, etc.
I already have every library this trash provides but I'm forced to go through it since a newb PHD wrote an image segmentation algorithm which should work just find with OpenCV/PointCloud/Cmake but NO he had to go put it in ROS and ruin my day.1 -
Cross post from /r/cscareerquestions
Hey guys how are you all doing!?
I got into university this September (Computer Engineering & Informatics).
Although I've been programming java since I was 14 (github.com/zarkopafilis), discussions with a friend who is a dot net guy and has been working full-time C# for 2 years now got me thinking.
Alright, Java's good. I've learned to love and hate the language. I also like Spring Boot and whole this ecosystem of stuff including Scala and the other Java based languages. Currently I'm in the proccess of completing some personal project of mine.
Alright, here's the big question: Assuming I am going to graduate (and start working) in 5-7-8 years (Masters, PhD - who knows), which language would you suggest I stick with and start learning? - for backend programming of course.
Don't tell me JavaScript. Although I don't like it I've digested the fact that I'll have to learn some of it for sure.
Currently that's what I'm thinking: Invest some more time learning how the JVM works (and probably keep improving my code quality). Also learn some more stuff regarding Spring Boot (and/or Web Services in general). Then advance onto Scala till couple of years pass. In that time I shall keep improving my SQL skills.
On the other hand I may start learning C# along with .NETcore .
Sidenote: Personally I prefer statically typed languages, that's why I dislike stuff like js and python although I occasionally find myself fiddling with small projects like some laser tracker written with python + opencv.
Sorry if this reads like a big disorganized dump of thoughts. Thanks in advance! :)3 -
OpenCV,OpenFace,Caffe are supported in Arch Linux,but CUDA is not supported!! :| WTF!! How these packages could be supported in Arch but CUDA not!7

I want to start a blog, and the name will be “I have a call degree/I am a programmer, but how do I”. Through this blog I want to share things I learned by my own, like seriously, nobody taught me to write full stack application, nobody taught me how to write opencv in c++, nobody taught me how to write a simple game, anyone has any suggestions?2

I just ended up making a program that shows news depending on the user's current emotions.
I implemented OpenCV and CK+ dataset to make this possible. Also, Feedparser for getting news. Now looking into PyQt for making all of this into a GUI app.
So happy that all of this was completed within a week and without much hitches. -
I remember using opencv already
and i remember tori and i discussing that the video frames are in what i later read as mat format.
and i remember thinking ..'sigh, whats the use'.
i wish i could have enjoyed the last number of years not pumped the strength out of my body just trying to survive and retain some semblance of intelligence meanwhile.
its a waste of time.
all of this, a complete waste of time and always has been.
and there is noone trustworthy to tell me what to do. noone who means anything but harm to everything and everyone.10 -
Anybody like to rip up CTF (or similar)? I've honestly never done a CTF before, I'd like to give jt a shot. I'll get my ass handed to me because I'm not back up to par on OpSec yet, but I adapt well and when I get into a nice groove I can make shit happen! (I like to think so, anyways haha!!)
I've been in full on dev mode lately and haven't had any time to Hulk Smash for a while... I went to fire up a new Kali live USB today and I couldn't run through the updates like I always have- they changed sooo much and I was pissed because I didn't have ethernet with me. That'll be another day for sure, but I still have my machine with Manjaro armed to the nutsack and back with the BlackArch rep. I def could use a break from the chaos, and getting my ass handed right to me sounds like an awesome time because learning is my favorite thing next to a possible chance at getting to destroy shit.
It's weird, because I'm sort of a n00b but also at the same time I've had computers ripped apart/jammed in my face since every day since I was 9 and Y2K was about to hit the fan lmao!! My hardware/network/layering knowledge is fuckin mint titties, I just can't code like a fuckin madman on the fly. I don't have a "primary" language, because I've been having to work with little bits of several languages for extended periods of time... I can at least find my way around all the dox without much of an issue and have no issue solving the probs I come across which is neat, but until the day comes where I can fuck a gaping hole through my keyboard on the fly like George Hotz during one of his lazy Sunday OpenCV SLAM/Python code streams all jacked up on Herba Mate hahahahaha!!!!
The dude uses fucking VIM and codes faster than anyone I've ever seen on levels of science/math so challenging I almost shit myself inside out when I catch one!!!! The level of respect I have for all my fellow red pills in here is as high as it gets, and that's one of the best parts about being a code junkie- sometimes ya get to cross paths with beastly, out of this world people that teach you so much without even having to explain shit.
If anyone's down, or maybe has some resources for me to check out so I can get my chops up let's make it happen -
[long confession/question]
So I was asked by a client to make an app similar to prisma(not exactly that but let's say a caricature app) and I knew I have to research a lot.
Now I have been loyal to PHP for over 5 years so I first tried with GD and imagick but the results were not very good, so I thought let's try opencv. I didn’t wanna make any compromises so I didn't go the bridging way, I worked on native python even though I am a newbie in it. I was fairly impressed with the cartoonizing results but others weren't. Soon I got to know that this would take much more than simple filter combinations or matrix manipulations.
I read about prisma and got to know it uses deep neural networks for the same.
Now, in the five years I have learnt almost all the things a run-of-the-mill "Full stack Web Developer" should know.
I have a fair knowledge of PHP, many of its frameworks, many js frameworks(obviously jquery), I have a very good understanding of CSS and its models, I have worked on some cool algos and found solutions to many problems but I haven't gotten to stage where I can implement neural networks/machine learning in my projects.
It just scares me.
___
A little back story: I have been the CTO of a small scale company for about 1.5 years now.
___
So all this got me to asking myself should I just step down from the post to a position where I can learn more skills. Managing takes a lot more time where I can't learn a lot. Sure I learnt some other important things but not as much tech knowledge as I would have in a more basic position.
I know not many of you must have read this far, but if you did what do you think I should do? Really depressed at the moment.5 -
I'm new in deep learning world, I want to develop a project regarding live text detection on mobile camera (without taking an image by the camera), can I do it by the tesorflow object detection api ? or with anyother tensorflow api or with opencv, which way is best? other suggestions are also welcome.

see now this is the f-ing shit that pisses me off.
There is this project named dain.
One time I made a project that dropped frames using opencv or ffmpeg i can't remember, creating a test output file and ran them through dain to benchmark it for myself.
alot of things just like this actually I tended to do to get a better sense. Its the reason I abandoned the NN since I think I have a feel for how to design them for certain tasks and remember that with my 'successes' i was still really far off from where i'd like to be.
additionally there are other kinds of ml that interest me more that I am not seeing too much on... point is
I worked all this crap out
got wavenet working to check on it YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARS ago and because the dirty fucks out west kept stealing my stuff, i end up back at square one waiting for some douchebag to steal my stuff again who isn't even going to do anything but pretend he's straight or pretend everything has some faggot meaning. its very annoying. why do these people live this way again ?3 -
You know a combination of trustworthy coders and retaining improvements would make my having to debug opencv build process unnecessary
Just saying god -

For who use OpenCV for work with pictures. highgui module spilted into videoio, imgcodecs and highgui itself :)
I had problem with new version of openCV after reinstalling new OS.
I wasn't able to capture image from Webcam, and i found that my Bashscript installed version 3.0 x)
All i needed to do for get Stream of pictures was...
#include <...opencv_videoio.hpp>
and for compile
g++ ... -lopencv_videoio -
Can anyone suggest me some open source projects? I went through a lot of articles where everyone said according to your interest you should select the project
I also went through this:
https://github.com/MunGell/...-
Still, I am finding it hard to select a project. I am intermediate in python, PHP, openCV, highly interested in OpenCV, cloud computing and web development.6 -
Trying to calibrate a gopro to remove fisheye effect with OpenCV.
The documentation of the script I'm using says "Lastly the program will calculate the total reprojection error. The closer this value is to zero the better. I usually like values under 0.1. Play around with the calibration, see what works and what improves it."
I spent all the afternoon recording video, extracting images and using the script. The lower error I got was 0.6, and the supposed undistorted image was actually more distorted than the original one.
So frustrated 😤 -
Thanks for your feedback. I was able to run Opencv on my computer and integrated with Arduino. I will greatly appreciate another feedback. My question is does anyone know the code for the functionality for the brightness and contrast filter?1

how do i get the installed numpy version for tensorflow that pip autoinstalled to not interfere with opencv which requires numpy >=1.2.0 ?
which btw i just installed.
and why is tensorflow a piece of crap ? LOL26 -
Is it just me or DOES RASPBIAN TAKE A FUCKING SHITLOAD OF TIME TO WRITE? WHEN THE FUCK AM I SUPPOSED TO INSTALL OPENCV NOW? I FUCKING HAVE CLASS TOMORROW WHICH IS NOW TECHNICALLY TODAY!1

I am new to python. I am working on a project and I am supposed to build sign language hand gestures using python and opencv. Does anyone have an idea on the procedures to take to get it done in 24hours?6

So I was building opencv some time back.
Nice enough package, like most python linked packages I'm finding though I know you can use it via c and its meant to be but why would you want to ? .. it contains a whole bunch of half finished crap that is actually useful in part including the capacity to tear apart video files and manipulate frames one at a time and then rewrite them back to a file. about the only lib that's easy to use that I saw that does that. hell I can even compose my own video frames. also the only other lib I saw that does that thus far.
so...
I post a bug, because of FUCKING CMAKE NOT WORKING. not conforming with the well thought out build environment that most GNU style c packages use.
you know like when you need an upstream source package to build the code, or a downgraded package to build the code and don't want to fuck up your host environment so you have to specify a bunch of lib paths and the like so that ld and gcc work correctly etc etc etc from your custom build location and so you can later use these same values to find the compiled lib and build software against it.
fucker closes my ticket saying i hijacked the c environment................
no.
its because cmake sucks.
they're using and i don't know why a module specifically written to find libtiff.
specifically written but doesn't find the only source on my system that provides tiff which my env variables point directly to !!!!
lazy fucking cocksuckers !
I want to code a solution this issue.
something that translates ac files and am files and cmakelists into something intelligent and easy to follow that doesn't sacrifice the flexibility of make and gnu shit and unfucks cmake based projects !7 -
So I am opencv curious. I started wondering how to train a recognition model for a particular part of the body. Everything I search wants to talk about body recognition and face recognition. I did find one article that talks about training say for hands or feet or body posture. So to satisfy my curiosity I am going to be playing with opencv this weekend. I think it will be fun!6

back into some quick and dirty opencv scripting for the afternoon to try to get a report out the door, and boyhave my variable names become, shall we say, gigidy inspiring:
longexposure = np.uint8(cumimage/float(len(ims)))
stacked = np.hstack({cumimage, longexposure}) -
Oh how familiar
Opencv is coaching me towards c++ to use dnn .
Under Linux this is not so annoying. Least most shit works under Linux related to c++2 -
have to use python and opencv for a uni project about lane detection in autonomous vehicles (just the detection with e.g. canny edge detection)
have begun to look into python in a 40min video seeing the differences between java and python, as i'm more comfortable in java....
well python is quite weird in its syntax but at the same time quite easy(?)
don't know what i should think about it 😕 as i'm used to the strict structure of java
any other good videos i can watch to get a better grasp of it?7 -

Need a programmer who has previously worked on nodejs/ opencv for facial recognition. Got an interesting idea.3 -
2 hours after resolving compatibility issues:
The following specifications were found to be in conflict:
- opencv==3.2.0 -> *[track_features=blas_openblas]
- opencv==3.2.0 -> harfbuzz=1.3 -> freetype[version='2.7|2.7.*'] -> libpng[version='>=1.6.22,<1.6.31']
- pillow==6.0.0
Well done for today. I'm going for a beer. Ah..almost forgot. Fuck you Anaconda and fuck you Python docs. -
Could any dev here explain how do u apply SVM to HOG features? I know what HOG features are but cannot for the life of me figure out how the hell to use them in an SVM -_-2

Finally managed to build a working Wordsearch system with OpenCV and curses.
I curse ncurses till the end of days. -
Live Color picker, I had developed this project almost a year ago. It was when I had started learning python. I wasn't aware of devrant back then so couldn't upload a rant for review.
But as they say it's never too late to start
I would like to have some reviews on this beginner project of mine. 😄

Do you recommend hiring junior or mid-level dev for a python role that involves mostly data transformations with pandas, growth and marketing projects like social media bots, consuming APIs for data and some experience with Azure SQL db? I’m worried if we hire too senior then they will leave as the role doesn’t involve any advanced software engineering, like caches, web apps, rest apis, etc. It’s more of a handyman that can automate and hack a solution to a business problem: for example, learning openCV to automatically crop thousands of images extracting only the text3
-
Anyone know how to get the type hints and doctags to show up in opencv in pycharm where it kind of seems like the build decided to make everything into cython objects ?
-
Do read my article on Live Color Detector using python. I would like some feedback from you guys.

It would be really helpful to me.3 -
Sophomore year starting soon so I'm looking for new project (s) to complete in parallel with the studies.
Some are more design-y and some more backend-y but I recently started getting better at designing so :)
1) Learn some fragment shader stuff. I've always been messing around with graphics and have a game on steam, so I think that's a good idea to be paired with signal processing.
2) Reactive web services. Preferably with spring-boot or vert.x but
3) I would also like to dive into golang (and make some reactive thing with it)
4) WebAssembly seems nice... But I got some concerns
5) exercise making wireframes -> CSS (with some js)
6) I've never really done any real backed work with nodejs, except serving and aot compiling js, or doing gulp tasks
7) Implementing a whole project, or a fraction of it as serverless on aws
* I'm definitely going to use a couple very simple services to make a docker swarm with load balancing, etc, just because I know how everything works but got no practical knowledge
8) Design an esports jersey for the university department I'm in (shouldn't take long)
So what do you guys think? Recommendations are welcome :)
P.S. last year in review:
> A webapp running on a raspberry pi powering a reflex testing game on gpio (java/spring-boot , codename: buttonmasher)
> small Elastic search cluster to monitor some random university servers through kibana dashboards
> laser tracking on wall of *any* colour and variable light conditions via a webcam (opencv) , controlling the mouse pointer, whether you run it against a projector or any wall
> jstrain.herokuapp.com => a small JavaScript powered tool with a DSL to help you train more efficiently without a coach
> Various random Photoshop stuff -
//not a rant, just a question
Yeah I know SO is the place to ask such stuff, but I still wanna ask it here.
I have started with OpenCV for image processing. The sad thing is it is available for python only. Is there a PHP alternative? The best I have found is ImageMagick which doesn't come close to OpenCV.
