TEMPLATE-MATCHING BASED ADAPTIVE BLOCK VECTOR RESOLUTION (ABVR) IN IBC - A simplified explanation of the abstract
This abstract first appeared for US patent application 18241071 titled 'TEMPLATE-MATCHING BASED ADAPTIVE BLOCK VECTOR RESOLUTION (ABVR) IN IBC
The abstract of the patent application describes a process where coding information indicates the application of an intra block copy (IBC) mode to a current block. This IBC mode triggers the retrieval of first adaptive block vector resolution (ABVR) information from the video bitstream. The ABVR information reveals that multiple block vector (BV) precisions are associated with the BV of the IBC mode. These precisions are then rearranged based on template matching (TM) differences between the current block and reference blocks. A specific BV precision is chosen from the reordered list based on TM differences, and the current block is reconstructed using this selected precision.
- The coding information triggers the application of an IBC mode to a current block.
- ABVR information from the video bitstream reveals multiple BV precisions associated with the BV of the IBC mode.
- TM differences between the current block and reference blocks are used to reorder the BV precisions.
- A specific BV precision is selected based on TM differences to reconstruct the current block.
Potential Applications: - Video compression technology - Image processing algorithms - Multimedia content creation tools

Original Abstract Submitted
Coding information is received and indicates that an intra block copy (IBC) mode is applied to a current block. Based on the IBC mode being applied to the current block, first adaptive block vector resolution (ABVR) information included in the coding information is obtained from the received video bitstream. The first ABVR information is determined to indicate that a plurality of BV precisions is associated with a block vector (BV) of the IBC mode. The plurality of BV precisions associated with the BV of the current block is reordered based on template matching (TM) differences between a template region of the current block and each of a plurality of template regions of reference blocks. A particular BV precision is selected from the plurality of reordered BV precisions by the TM differences. The current block is reconstructed based at least on the selected particular BV precision.
