METHOD AND DEVICE FOR ESTIMATING MOTION BETWEEN TELEVISION FRAMES IN A FRAME SEQUENCE

摘要

A method and a device for estimating motion between television frames, wherein current and estimate comparison frames are converted into corresponding coarse frames, and auxiliary motion vectors (1) are established on the basis of coarse current and estimate comparison frames by block estimation, at least one auxiliary motion vector being established and combined with each macroblock (MB). Final motion vectors (2) are established for each macroblock (MB) of the current and original estimate comparison frames on the basis of the auxiliary motion vectors. The method and device are useful for data compression within the framework of the MPEG standard.
