Title:
INTRA MODE CODING USING MODE USE STATISTICS TO GENERATE MPM LIST
Document Type and Number:
WIPO Patent Application WO/2019/137732
Kind Code:
A1
Abstract:
A method for encoding or decoding a video sequence is provided. In some embodiments the method includes, for each intra prediction mode (IPM) included in a certain set of IPMs, assigning a priority value to the IPM. The method also includes, deriving an intra prediction characteristic based on the priority values assigned to the IPMs, and using the derived intra prediction characteristic in a video sequence encoding process and/or a video sequence decoding process.
