I'm looking for an algorithm, that would do image comparisons at real time, basically on images acquired from a webcam (like 30 frames/second). My current implementation is pretty slow, tired to improve it by dropping a few frames and reducing the resolution -- but with no success.

So, I'm exploring options like using better algorithms like Key-point Matching etc. And on a different note, I'm also looking for a GPU based image comparison sample implementations (either DirectX or OpenGL APIs).

Have you tried Perceptual Image Diff?
