You mean something like chromakeying? jitter tutorial 10
Otherwise you can take a look into the shaders on:
/Max5/Cycling '74/jitter-shaders/composite in particular co.chromakey.jxs and co.difference.jxs

jxs are wrappers for shaders. A shader is a small program used to create your own visual effects:
http://en.wikipedia.org/wiki/Shader

as always the jitter tutorials are the best reference: take a look into the numbers 41 and 42.

You can read this super nice article in writing shaders inside jitter:

herewith a super simple example. You can do a chain of effects in-between the jit.gl.texture and the jit.gl.videoplane
