My professor asked for some images of cool stuff I worked on for a presentation he is giving. So here is me moving fast enough to cause motion blur :) The code is using the camera to detect people, and then project the bounding box down in the lidar frame, and mask all the lidar points within that cone.
Anyway, if someone is familiar with super fast agglomerative clustering code in C++ (or even python, if it's efficient), please share it with me!
