FLIPPING MODE FOR CHROMA AND INTRA TEMPLATE MATCHING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18382922 titled 'FLIPPING MODE FOR CHROMA AND INTRA TEMPLATE MATCHING
Simplified Explanation: The patent application describes a method for reconstructing a block in a video stream using a flip mode, where the locations of samples within the block are adjusted. This is achieved by selecting a reference block from candidate blocks in a reconstructed region of the picture based on template matching costs, and then reconstructing the block based on the selected reference block.
- The method involves receiving coding information for a current block in a video stream.
- The coding information indicates that the block is coded using a flip mode.
- A reference block is determined from candidate blocks in a reconstructed region of the picture based on template matching costs.
- The reconstruction block is determined based on the selected reference block.
- The current block is reconstructed by adjusting the locations of samples within the reconstruction block based on the flip mode.
Potential Applications: This technology can be applied in video compression algorithms, video streaming services, and video editing software.

Original Abstract Submitted
A video bitstream comprising coding information of a current block in a current picture is received. The coding information indicates that the current block is coded by a flip mode in which locations of samples of the current block are adjusted within the current block. A reference block is determined from a plurality of candidate reference blocks in a reconstructed region of the current picture for the current block based on template matching (TM) costs. The TM costs indicate differences between a template of the current block and respective templates of the plurality of candidate reference blocks. A reconstruction block of the current block is determined based on the determined reference block. The current block is reconstructed by adjusting locations of samples of the reconstruction block within the reconstruction block based on the flip mode.
