Search - "character detection"

So in Telegram there is this funny little game called Lumberjack where you need to click left and right to cut the branches. My and my fellow students played this in the group. Then I got bored for like 30 minutes and decided to write a little bot which checks where the branches are with pixel detection and sends a left/right click to the window. Imagine my friends faces when all of sudden my score was 500+ and the character ran through this like a fucking jackhammer :D

Ladies and gentlemen, prepare yourselves for a rant with a capital R, this is gonna be a long one.
Our story begins well over a year ago while I was still in university and things such as "professionalism" and "doing your job" are suggestions and not something you do to not get fired. We had multiple courses with large group projects that semester and the amount of reliable people I knew that weren't behind a year and in different courses was getting dangerously low. There were three of us who are friends (the other two henceforth known as Ms Reliable and the Enabler) and these projects were for five people minimum. The Enabler knew a couple of people who we could include, so we trusted her and we let them onto the multiple projects we had.
Oh boy, what a mistake that was. They were friends, a guy and a girl. The girl was a good dev, not someone I'd want to interact with out of work but she was fine, and a literal angel compared to the guy. Holy shit this guy. This guy, henceforth referred to as Mr DDTW, is a motherfucking embarrassment to devs everywhere. Lazy. Arrogant. Standards so low they're six feet under. Just to show you the sheer depth of this man's lack of fucks given, he would later reveal that he picked his thesis topic "because it's easy and I don't want to work too hard". I haven't even gotten into the meat of the rant yet and this dude is already raising my blood pressure.
I'll be focusing on one project in particular, a flying vehicle simulator, as this was the one that I was the most involved in and also the one where shit hit the fan hardest. It was a relatively simple-in-concept development project, but the workload was far too much for one person, meaning that we had to apply some rudimentary project management and coordination skills that we had learned to keep the project on track. I quickly became the de-facto PM as I had the best grasp on the project and was doing a lot of the heavy lifting.
The first incident happened while developing a navigation feature. Another teammate had done the basics, all he had to do was use the already-defined interfaces to check where the best place to land would be, taking into account if we had enough power to do so. Mr DDTW's code:
-Wasn't actually an algorithm, just 90 lines of if statements sandwiched between the other teammate's code.
-The if statements were so long that I had to horizontal scroll to see the end, approx 200 characters long per line.
-Could've probably been 20 normal-length lines MAX if he knew what a fucking for loop was.
-Checked about a third of the tiles that it should have because, once again, it's a series of concatenated if statements instead of an actual goddamn algorithm.
-IT DIDN'T FUCKING WORK!
My response was along the lines of "what the fuck is this?". This dipshit is in his final year and I've seen people write better code in their second semester. The rest of the team, his friend included, agreed that this was bad code and that it should be redone properly. The plan was for Mr DDTW to move his code into a new function and then fix it in another branch. Then we could merge it back when it was done. Well, he kept on saying it was done but:
-It still wasn't an algorithm.
-It was still 90 lines.
-They were still 200 characters wide.
-It still only checked a third of the tiles.
-IT STILL DIDN'T FUCKING WORK!
He also had one more task, an infinite loop detection system. He watched while Ms Reliable did the fucking work.
We hit our first of two deadlines successfully. We still didn't have a decent landing function but everything else was nice and polished, and we got graded incredibly well. The other projects had been going alright although the same issue of him not doing shit applied. Ms Reliable and I, seeing the shitstorm that would come if this dude didn't get his act together, lodged a complaint with the professor as a precautionary measure. Little did I know how much that advanced warning would save my ass later on.
Second sprint begins and I'm voted in as the actual PM this time. We have four main tasks, so we assign one person to each and me as a generalist who would take care of the minor tasks as well as help out whoever needed it. This ended up being a lot of reworking and re-abstracting, a lot of helping and, for reasons that nobody ever could have predicted, one of the main tasks.
These main tasks were new features that would need to be integrated, most of which had at least some mutual dependencies. Part of this project involved running our code, which would connect to the professor's test server and solve a server-side navigation problem. The more of these we solved, the better the grade, so understandably we needed an MVP to see if our shit worked on the basic problems and then fix whatever was causing the more advanced ones to fail. We decided to set an internal deadline for this MVP. Guess who didn't reach it?
Hitting the character limit, expect part 2 SOON7 -
Went to a hackathon and tried to use ARCore. Most painful experience of my life. There are so many issues and critical bugs that I can't even fit them all into a 5000 character rant, Google has shittier code than a highschool startup.
So instead of typing 5000 characters I'll just save you all some time. If you're forced to use ARCore, don't even try to use the AcquireCameraImageBytes or related apis for actually accessing the camera feed. Just use unity's screen capture API (draw an invisible rectangle on the whole screen, make a texture, readPixel entire rectangle). Turning off all models for 1 frame and taking a screen capture is easier, faster, and somehow more optimal than using Google's code.
Also, they released Augmented Faces on Friday. Their demo plainly doesn't work the way they intended on many devices because the list never gets populated since their engineers are dumb fucks. Just force the face mesh to always remain active and you'll instantly support all devices! You can deactivate it using your own methods but Google's doesn't work on many devices. There's an issue in their repo about this that they are plainly ignoring.
Also if you're interested I have a (working?) engine to use Object Detection for interactions within AR + a create your own adventure game demo made w/ object detection + ar on my git:
https://github.com/pshah123/...
My code is 100% crap so definitely don't use it in production but I was able to get the individual pieces working so hopefully this helps someone! Unless you're from Google, then fuck you please uninstallrant please uninstall google fuck google mv google /dev/null sudo rm google sudo kill -9 google git rm google16 -
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.
