METHOD AND APPARATUS FOR BLOCK-BASED MOTION ESTIMATION

摘要

Provided is a method and apparatus for block-based motion estimation, in which a motion vector is estimated by allocating different search points for blocks in a frame having a plurality of block groups. A video motion estimation method includes allocating different search points for blocks in each block group of an input video frame, estimating candidate motion vectors for the blocks by measuring the degree of block distortion between frames at each of the allocated search points, and measuring the degree of block distortion to which each of the estimated candidate motion vectors is applied , by applying the estimated candidate motion vectors to a current block, and determining the candidate motion vector having the minimum degree of block distortion to be a final motion vector of the current block.
