    摘要: Methods and apparatus are provided for efficient video encoding and decoding of intra prediction mode. An apparatus includes a video encoder for encoding picture data for at least a block in a picture by determining a spatial pattern for a decoded intra prediction mode residue used to reconstruct the picture at the video encoder. The decoded intra prediction mode residue is obtained by inverse quantizing and inverse transforming a transformed and quantized difference between an original version of the block and at least one reference block. The spatial pattern is used to determine an intra prediction mode for encoding the block.

    摘要: Methods and apparatus are provided for adaptive residual updating of template matching prediction for video encoding and decoding. In one embodiment, an apparatus and method encodes picture data for at least a block in a picture using template matching prediction, wherein the template matching prediction involves selecting from among a plurality of residual updating schemes for use in encoding the block. In another embodiment, an apparatus and method encodes a block in a picture using template matching prediction, wherein the template matching prediction involves partitioning the block into a plurality of sub-blocks, and applying a transform to a residual of a particular sub-block from among the plurality of sub-blocks subsequent to searching for a prediction for the particular sub-block block and prior to completion of processing of the block with respect to the template matching prediction.
