That is quite a standard thing. For graphics images, any connected pixel
must have the same pixel value with the seed (root) pixel. For grayscale images, the absolute difference between a pixel on the path and the seed pixel should be less than same threshold (usualy 64). Similar criteria can be found for color images using a distance of 3-D vectors (RGB). The path (or the conectedness) can be checked using the regular 4- or 8-connectedness. As for links... the algorithm is so simple, do you need one? I would be surprised if google didn't yield many useful links, though.
