This paper presents an edge-enhancing super-resolution algorithm using anisotropic diffusion technique. Because we solve the super-resolution problem by incorporatinganisotropic diffusion, our technique does more than merely reconstruct a high-resolutionimage from several overlappingnoisy lowresolution images and preserve them. In addition to reducing image noise during the restoration process, our method also enhances edges. We apply this technique to a video stream which can be aligned by 3x3 projective transformations.
