Title:
METHOD AND APPARATUS FOR DIMD REGION-WISE ADAPTIVE BLENDING, AND ENCODER/DECODER INCLUDING THE SAME
Document Type and Number:
WIPO Patent Application WO/2023/193550
Kind Code:
A1
Abstract:
A method of deriving a Decoder-side Intra Mode Derivation, DIMD, predictor for respective samples of a coding unit, CU, of a picture is described. The method includes selecting one or more Intra Prediction Modes, IPMs, in a template area adjacent to the CU, determining blending weights for blending at least the one or more selected IPMs, and generating the DIMD predictor by blending the one or more selected IPMs using the determined blending weights for the CU so that the blending varies over the CU.
