Background / Foreground Segmentation

advanced
#1

Hello all,

Has somebody experience with modeling a background for a background subtraction algorithm? I tested a few algorithms in opencv, but not in openFrameworks!
I think the simplest solution is to subtract the current frame from a defined background frame! But I should have an advanced one. I studied the two algorithms in the ‘Learning OpenCV’ book (Averaging Background Method, Codebook Method). Has somebody an implementation in openFrameworks?

Or are there better algorithms for background subtraction?

Best,
Christian

there a bit on background subtraction in this post.

try the motion detection code… it uses this technique.

might be cool to add to ofxOpenCv. Keep us posted.

Hi Christian,

I have read your post! probably you can help me out! I don’t really understand how the codebook works? probably can you give me a brief explaination? it will be best if you can provide me the source codes?? many thanks

Cheers,
Angeline

Hi
