SUPER-TRANSFORM VIDEO CODING

Super-transform coding may include identifying a plurality of sub-blocks for prediction coding a current block, determining whether to encode the current block using a super-transform, and super-prediction coding the current block. Super-prediction coding may include generating a super-prediction block for the current block by generating a prediction block for each unpartitioned sub-block of the current block, generating a super-prediction block for each partitioned sub-block of the current block by super-prediction coding the sub-block, and including the prediction blocks and super-prediction blocks for the sub-blocks in a super-prediction block for the current block. Including the prediction blocks and super-prediction blocks for the sub-blocks in a super-prediction block for the current block may include filtering at least a portion of each prediction block and each super-prediction block based on a spatially adjacent prediction block. Super-transform coding may include transforming the super-prediction block for the current block using a corresponding super-transform.
