Algorithm for image search in another image. (Collage)

Is it possible? I have one huge image, 80mb with many tiny pictures. They are tilted and wrapped. How can I find an image using programming? I know how to use java and C ++. How would you do that?

One algorithm I used earlier is SIFT . If you are interested in implementing the algorithm for yourself, you can see the course notes for CPSC 425 in UBC , which details how to implement SIFT in MATLAB. If you just need code that does this, check out VLFeat , the C library that runs SIFT and a number of other algorithms.

Quote from Jerry Coffin:

Edit: That's right - it is patented, and I probably should have mentioned this for a start. In case anyone takes care of this in US Patent # 6,711,293 .
