Abstract
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.
