Does anyone know of an avisynth filter that will help smooth a certain hue? I should explain more... I have a background that is mostly one color (green), it is a poorman's chroma green screen. It is made of cloth and has a few wrinkles which are causing the problem. I would like a filter that would smooth out the background to more of the same solid color, but doesn't blur, smooth, or effect the subject in the foreground (which contains no green). Is there such a filter that might help?

Thanks in advance.
