摘要:
Methods and apparatus are provided for adaptive transform selection for video encoding and decoding. An apparatus includes a video encoder for encoding at least a block in a picture using a transform. The transform used to encode the block is selected from a plurality of transforms. The plurality of transforms is adaptively updated during the encoding of the picture.
