METHOD FOR MOTION ESTIMATION OF VIDEO FRAME, AND VIDEO ENCODER USING THE SAME

摘要

Provided are a method for motion estimation of a video frame and a video encoder using the method. The method includes providing a low-resolution frame by down-sampling a video frame to be motion estimated, estimating motion vectors for blocks of the low-resolution frame, and creating initial values used to estimate motion vectors for blocks of a high resolution frame by up-sampling the blocks of the low-resolution frame.
