Title:
INTRABC USING WEDGELET PARTITIONING
Document Type and Number:
WIPO Patent Application WO/2023/076505
Kind Code:
A3
Abstract:
This disclosure relates generally to video coding and particularly to intra block copy coding mode using wedgelet partitioning. For example, a method is disclosed for processing video data which may include receiving a video bitstream comprising a current block of a video frame; extracting an IntraBC flag from the video bitstream indicating that the current block is predicted under an IntraBC mode; determining from the video bitstream that the current block is partitioned under a wedgelet partitioning mode, wherein the current block is partitioned into a plurality of partitions comprising a first partition and a second partition; identifying at least the first partition and the second partition of the current block; determining a first block vector for predicting the first partition and a second block vector for predicting the second partition, respectively; and decoding the current block based on at least the first block vector and second block vector.
