Video encoding and decoding methods and apparatuses using mesh-based motion compensation

摘要

A video encoding and decoding method and apparatus using mesh-based motion compensation are provided. The video encoding method based on motion compensation includes making a coding priority map representing at least one block to be encoded prior to other blocks among all blocks in a current image based on an error between the current image and a reference image and a predetermined bitrate, and encoding the at least one block represented on the coding priority map among the blocks in the current image.
