I would like to write a simple program which processes the depth feed from an Asus xtion depth sensor using OpenNI. The sensor will be fixed like a CCTV camera and count multiple targets moving around.
The processing would involve some simple functions on each frame (background subtraction, level sets, connected components filter), and some multi-target tracking across frames. I have searched the web, but it is hard to see how best to get started (and I'm also quite new to programming in C).
Can anyone recommend any existing code that can help to get started / any libraries which would be suitable for this real-time application? Or perhaps there is some opensource code which already does such a thing? Would really appreciate any pointers from anyone with experience. Thanks!
