摘要:
A method for processing a selected portion of a video, the selected portion of the video having a plurality of blocks. The method includes obtaining current prediction parameters for all of a plurality of adjacent blocks from the plurality of blocks that are adjacent to a current block from the plurality of blocks in the selected portion of the video, generating a base prediction for the current block from the plurality of blocks using the current prediction parameters associated with the current block, identifying adjacent prediction parameters from the current prediction parameters for a first adjacent block from the plurality of adjacent blocks, determining an overlap region within the current block and adjacent to the first adjacent block, and generating, for each pixel within the overlap region, an overlapped prediction for the pixel as a function of the base prediction and a prediction based on the adjacent prediction parameters.
