CE4-related: Adaptive Motion Vector Resolution for Affine Inter Mode
Authors: H. Liu ByteDance Li Zhang ByteDance Kai Zhang ByteDance Yifan Wang ByteDance P. Zhao ByteDance D. Hong ByteDance
Abstract
This contribution extends Adaptive Motion Vector Resolution (AMVR) to affine inter mode, wherein one MV resolution could be selected from a set of MV resolutions. In this proposal, the motion vector resolution set includes 1/16-pel, 1/4-pel and 1-pel. Simulation results reportedly show 0.36% BD-rate saving in Random Access (RA) configuration with 2% decoding running time increase. Moreover, if AMVR is disabled in non-affine inter mode, proposed method can achieve 0.58% BD-rate saving in RA configuration with 1% decoding running time increase.
