    How I can implement this algorithm? I found this algorithm is not very easy for it. Can anyone give me some idear. Before i found several question about nearest color. FindNearestColor{...} maybe color texture is used ? face1 and face2 ,match face2's colour into face1. I know this is not very easy. How about this algorithm?? thanks :)

    Everything will be happy!

      I'm not very familiar with photoshop or this particular function is but since no one else has answered I'll try and help you but I may be misunderstanding the question. Colors are normally represented as 3 bytes. One for red, one for green, and one for blue (RGB)and all colors are a mixture of those 3 values. So if I understand the question right all you would need to do is get those values and then compare them. Maybe you could elaborate on what this Photoshop function does and more people would be able to help you.

        Face detection is quite a complex subject and requires a fair amount of research. However there are some libraries available which you can probably find via Google.
