Method and system for motion estimation using chrominance information |
摘要 |
A method and system for motion estimation using chrominance information, which is based on each block of a current frame to find a corresponding block from a previous frame within a search area and accordingly determines a motion vector and includes first separately computing luminance differences and chrominance differences between luminance and chrominance of a target block in a current frame and luminance and chrominance of candidate blocks in a search range of a previous frame, next adjusting the luminance differences based on the first chrominance differences and the second chrominance differences and outputting adjusted luminance differences; and finally finding a minimum one among the adjusted luminance differences and accordingly determining the motion vector.
