  • INTRA SUB PARTITIONS FOR VIDEO ENCODING AND DECODING COMBINED WITH MULTIPLE TRANSFORM SELECTION, MATRIX WEIGHTED INTRA PREDICTION OR MULTI-REFERENCE-LINE INTRA PREDICTION
    Publication number: 20230024223
    Abstract: In an encoding apparatus or a decoding apparatus, an encoding method or decoding method combines various coding tools with intra sub partitioning mode in which a coding unit is split in multiple sub partitions. At least one embodiment particularly aims at the selection of primary transforms among a set of multiple transforms for video encoding or decoding of intra sub block partitions. At least one embodiment particularly aims at intra coding using Ma-trix-Based Intra Prediction mode combined with Intra Sub Partition mode. At least one embodiment particularly aims at intra coding using Multi-Reference-Line intra prediction mode combined with Intra Sub Partition mode.

  • METHOD AND DEVICE FOR PICTURE ENCODING AND DECODING
    Publication number: 20220030238
    Abstract: A decoding method is presented. a type of split of a block into transform units is first decoded. A transform is then determined for each transform unit of said block responsive to said type of split. Finally, decoded transform coefficients of said transform units are inverse transformed using the determined transforms.
