WebDemonstration of image registration using optical flow. By definition, the optical flow is the vector field (u, v) verifying image1 (x+u, y+v) = image0 (x, y), where (image0, image1) is a couple of consecutive 2D frames from a sequence. This vector field can then be used for registration by image warping. To display registration results, an RGB ...
