In a video processing system scene shifts are detected and the need for adjusting the brightness between pairs of adjacent frames of a video motion picture is assessed. The need for brightness adjustment is assessed and a possible scene shift is detected by identifying homogeneous pixels in at least one frame of a pair of adjacent frames of the motion picture. The brightness of one of the adjacent frames is then adjusted and a scene shift is detected based on the ratio of the number of homogeneous pixels undergoing a substantial change in brightness relative to the total number of homogeneous pixels identified. When a need for a brightness adjustment is determined the brightness of one of the frames is adjusted before estimating optical flow between the frames.

Method and system for the estimation and compensation of brightness changes for optical flow calculations

A method for estimating a motion field from a first image with a corresponding first shape to a second image with a corresponding second shape, wherein a hypothesis motion field is given and the motion fields have one motion vector for each valid pixel or valid block of pixels in the first image.
