EE2-3.12a: History-parameter-based affine model inheritance
Authors: Kai Zhang ByteDance Li Zhang ByteDance Zhipin Deng ByteDance N. Zhang ByteDance Yifan Wang ByteDance
Abstract
This contribution presents the EE2-3.12a test results for history-parameter-based affine model inheritance (HAMI) proposed in JVET-X0088. With HAMI, affine parameters of previously affine-coded block have been stored in a History-Parameter Table (HPT). New affine merge and AMVP candidates as well as new regular merge candidates can be constructed with affine parameters fetched from HPT and base MVs fetched from neighbouring blocks, and put into the sub-block-based merge candidate list, the affine AMVP candidate list and the regular merge candidate list, respectively. On top of ECM-3.1, simulation results of the proposed method are reported as below:
