    摘要: Methods and apparatus are provided for video encoding and decoding using adaptive geometric partitioning. An apparatus includes an encoder for encoding picture data for a region in a picture using adaptive geometric partitioning, wherein a subset of geometric partitions used to code the picture data for the region is determined responsive to at least one of a distance and an angle. The distance is measured from a defined point within the region to a partition boundary. The angle is measured with respect to at least a line extending from the defined point within the region to the partition boundary.

    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 coding of motion information. An apparatus includes an encoder for encoding at least a block in a picture using a motion vector. An adaptive motion vector accuracy scheme is used to select an accuracy of the motion vector used to encode the block. Selection criteria for selecting the accuracy for the motion vector include non-rate-distortion-based criteria.
