Title:
SYSTEMS AND METHODS FOR GEOMETRY-ADAPTIVE BLOCK PARTITIONING OF A PICTURE INTO VIDEO BLOCKS FOR VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2019/004364
Kind Code:
A1
Abstract:
A method of partitioning video data for video coding is disclosed. The method comprises receiving a video block which includes sample values for a component of video data, partitioning the video block according to a partitioning line which is defined according to an angle and an distance, and signaling the partitioning line based on allowed values for the angle and the distance. The allowed values are based on one or more of properties of video data or video coding parameters.
