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.
