We present super-resolution methods that enhance image contrast and perform anisotropic diffusion simultaneously. Since we solve the super-resolution problem by encouraging Mach-band profiles while incorporating anisotropic diffusion, our technique not only reconstructs a high-resolution image from several overlapping noisy low-resolution images, but also enhances edges and image contrast while suppressing image noise during the restoration process. We apply this technique to a video stream, which can be aligned by 3×3 projective transformations. © 2003 SPIE and IS&T.
