Not sure if you are trying to do a "this picture file is a duplicate file of this picture file" or if you're tyring to do some sort of image recognition so I don't know if this is what you are asking for.

If you are just looking at two files to see if they are duplicates one thought I have is to do an MD5 sum on the two files and see if the hash matches. If they match chances are they are the same image. If not they are definitely not hte same image.
