Inverse chroma key

Hi guys

I want to view just one color, and then use contour to get only this color tracked. is there any patch or shader that can filter everything except one color?

But not with a background texture as reference like BG+Key or background supression, because this are kind of"static" methods, and if Im allways refreshing the background, the contour would be flickering or at least not working smooth.

any ideas?

maybe the ColorTracker can do that for you?

have a close look at SiftHSV (EX9.Effect) .

i can imagine this being very useful for you.
