Finding similar images is not at all a trivial task. Entire PhD dissertations have been committed to it. The solutions are still very unreliable as of yet. If you want to find more, you can read the research out of the ongoing Image CLEF track. I worked with them briefly a couple of years ago in co

I did this once for a motion dection algorithm. I used luminescence calculations to determine this. I basically broke the image into a grid of nine (3x3) areas and calculated the luminescene for each section and if it changed signficantly enough then there has been motions. The more sections, th
