Non-CE4: On BDOF and PROF parameter derivation
Authors: Xiaoyu Xiu Kwai Yi-Wen Chen Kwai T.-C. Ma Kwai Hong-Jheng Jhu Kwai X. Wang Kwai
Abstract
In this contribution, two modifications are proposed to unify the intermediate parameter derivation process of the BDOF and PROF: 1) align the motion refinement precision of the PROF to be the same as the BDOF, i.e., 1/32-pel, as proposed in CE4-2.1; 2) remove the dependency of internal bit-depth on the calculation of intermediate parameters of the BDOF and PROF. Compared to VTM-6.0 anchors, the proposed modifications reportedly show average BD-rate changes of {0.01%, 0.02%, 0.01%} and {0.02%, 0.01%, 0.04%} for RA and LD configurations, respectively.
