Abstract
An image decoding method is disclosed in the present specification. An image decoding method according to the present invention may comprise determining a prediction mode of a current block and performing prediction with respect to the current block on the basis of the determined prediction mode.
Claims18
An image decoding method comprising:
- determining a prediction mode of a current block;
- and
- performing prediction for the current block based on the determined prediction mode,
- wherein two prediction blocks are generated for the current block,
- wherein a final prediction block for the current block is generated using a weighted-sum using the two prediction blocks,
- wherein a size of each of the two prediction blocks is equal to a size of the current block,
- wherein a weight-pair comprising a first weight and a second weight is selected from a plurality of weight-pairs for the weighted-sum,
- wherein the first weight of the selected weight-pair is applied to each sample of a first prediction block of the two prediction blocks, and
- wherein the second weight of the selected weight-pair is applied to each sample of a second prediction block of the two prediction blocks.
