Hi again,

I've read several papers and it appears that i might have a problem
even if i succeed in implemtning this algorithm. Their work is based
on a pixel codebook based on a "color distorsion metric" with a
brigthness ratio. Since i'm working on gray level frames the method
cannot work.
I would like to know if someone has read this paper, or have an idea
on this method.

I would also like to know if someone has already heard about
background/foreground segmentation using kohonen ?
