If you struggle finding an Avisynth solution to this, Imagemagick can provide pixel value and coords via its PPM image format tools, you can convert an image to a text file list of RGB values and there locations as well as thresholding first to capture only certain pixel locations and values.

Although the download link is to geocities (which has now gone), looks like the filter can be obtained from http://avisynth.org/warpenterprises/ |
