CE4: History-based Motion Vector Prediction (Test 4.4.7)
Abstract
This contribution presents a History-based Motion Vector Prediction (HMVP) method for inter coding. In HMVP, a table of HMVP candidates is maintained and updated on-the-fly. After decoding a non-affine inter-coded block, the table is updated by adding the associated motion information as a new HMVP candidate to the last entry of the table. Constrained FIFO rule is applied to remove and add entries to the table. The HMVP candidates could be applied to either merge candidate list or AMVP candidate list. It is asserted that the line buffer size is kept unchanged compared to VTM. Simulation results reportedly show that HMVP with 6 entries of the table achieves 0.58%, 0.72% and 0.78% BD rate reduction for RA Main10 configuration with merge list size equal to 6, 8, and 10, respectively. When HMVP is only applied to the merge mode, it reports 0.43%, 0.59% and 0.65% BD rate reduction for RA Main10 configuration with merge list size equal to 6, 8, and 10, respectively.
