Abstract
An apparatus includes processing circuitry configured to determine a plurality of candidate prediction blocks for a current block based on a cost value between a template of each of the plurality of candidate prediction blocks and a template of the current block according to an intraTMP. The processing circuitry is configured to determine a plurality of masks for the plurality of candidate prediction blocks. The respective mask for each candidate prediction block of the plurality of candidate prediction blocks includes a respective weighting matrix having a plurality of weighting values. The processing circuitry is configured to reconstruct the current block based on a fused prediction block, the fused prediction block being a sum of the weighted prediction blocks. Each weighted prediction block is equal to a product of a mask of a respective candidate prediction block of the plurality of candidate prediction blocks and the respective candidate prediction block.
