US Patent 11765345 Multiple prediction blocks for one intra-coded block

Devices, systems and methods for digital video processing, which includes multiple prediction blocks for one intra-coded block, are described. In a representative aspect, a method for video processing includes generating a final prediction block for a conversion between a current block of visual media data and a bitstream representation of the current block and performing the conversion based on the final prediction block. At least a portion of the final prediction block is generated based on a combination of a first prediction block and a second prediction block that are based on reconstructed samples from an image segment that comprises the current block.
