摘要： A video decoding method for decoding a target block using intra prediction comprises decoding, from a bitstream, boundary line information specifying at least one boundary line for partitioning the target block. The boundary line information allows partitioning the target block into a plurality of non-rectangular blocks. The method further comprises determining intra prediction modes for the non-rectangular blocks based on the boundary line information; generating a prediction block of the target block by performing intra prediction on each of the non-rectangular blocks using the intra prediction modes; reconstructing a residual block of the target block from the bitstream; and reconstructing the target block by adding the prediction block and the residual block.

摘要： The present disclosure is related to an intra prediction method and an apparatus using block copy based on geometric transform. The intra prediction method and apparatus derive a reference block vector at each vertex of a current block and perform a geometric transform on the reference block vectors to generate reference blocks of various shapes that are not constrained to rectangular shapes. The intra prediction method and apparatus calculate a sub-block-vector for each pixel or group of pixels of the current block using the reference block vectors.
