Title:
MOTION CANDIDATE LIST CONSTRUCTION FOR PREDICTION
Document Type and Number:
WIPO Patent Application WO/2020/098713
Kind Code:
A1
Abstract:
A method of encoding or decoding video includes: inserting motion candidates in a motion candidate list of a video region of a video block using a list derivation rule, wherein the video region has a geometry shape that is a non-square and non-rectangular shape; and performing a conversion between the video block and a bitstream representation of the video block using the motion candidate list, wherein the list derivation rule comprises one or more selected from a group consisting of: rule 1: generating uni-prediction motion candidates from bi-prediction regular motion candidates using a non-scaled averaging; rule 2: generating motion candidates by scanning a list of regular motion candidates at most M times, where M is an integer less than 4; rule 3: performing a pruning step during the inserting wherein the pruning step is aligned with another pruning step performed for a regular motion candidate list for a second video block which is coded with non-geometry partitions; rule 4: performing a partial pruning step during the inserting, wherein the partial pruning limits comparison with less than all available motion candidates for the partial pruning step.
