BLOCK-BASED OPTICAL FLOW ESTIMATION OF MOTION PICTURES USING AN APPROXIMATE SOLUTION

摘要

According to another aspect of the present invention, there is provided a method for estimating an optical flow of a reference image, the method comprising: dividing the reference image into a plurality of reference blocks; Determining whether an optical flow of each of the reference blocks should be estimated; Estimating an optical flow of reference blocks to which an optical flow should be estimated as a result of the determination; And estimating an optical flow of the reference image based on the optical flows of the estimated reference blocks.
