Non-CE: An improvement to hash-based motion estimation
Abstract
This document presents an improvement to hash-based motion estimation. In the proposed method, all rectangle block can perform hash-based motion estimation without building corresponding hash map. In addition, we reuse the MV of hash mode to initialize the MV in the normal motion estimation. For TGM sequences, experimental results report 1.01% and 2.04% coding gain for RA and LD_B, with encoding time reduced to 92% and 92%. The anchor is VTM-4.0 and IBC is off. If IBC is on, 0.65% and 1.43% coding gain is reported, with encoding time reduced to 91% and 95%.
