METHOD OF LOOKING FOR MOTION VECTORS OF LATTICE POINTS IN WARPING ESTIMATION CODING

摘要

The present disclosure relates to a method of obtaining a motion vector of grid points in warping prediction encoding. The method of obtaining a motion vector of grid points in a moving image encoder having a warping prediction mode includes: (1) a motion vector of blocks divided into constant sizes; And (2) calculating motion vectors of the grid points by averaging the motion vectors of the blocks including the grid points, based on the motion vectors of the blocks obtained in the first step (1). . This method has the effect of reducing the amount of computation and increasing the coding efficiency for motion prediction mode selection in a moving picture encoder having a warping prediction mode.
