Flipped Templates for Reconstruction-Reordered Intra Block Copy - A simplified explanation of the abstract

This abstract first appeared for US patent application 18521166 titled 'Flipped Templates for Reconstruction-Reordered Intra Block Copy

Simplified Explanation

The patent application describes a method for encoding and decoding blocks based on a reference block flipped relative to the current block. The method includes entropy encoding a parameter value indicating whether a reference block matches a predictor value, which is selected from multiple candidates based on associated costs.

• The innovation involves encoding and decoding blocks using a reference block flipped relative to the current block.
• The method includes entropy encoding a parameter value indicating whether a reference block matches a predictor value.
• The predictor value is selected from multiple candidates based on associated costs.
• Costs are determined by comparing templates of candidate reference blocks with the template of the current block.

Potential Applications

The article does not detail the specific costs associated with each candidate reference block.

Original Abstract Submitted

A current block may be encoded/decoded based on a reference block flipped relative to the current block. An indication of whether a value of a parameter (e.g., a block vector difference) indicating the reference block matches a value of a predictor for the parameter (e.g., a block vector difference predictor) may be entropy encoded. The predictor may be selected from among a plurality of candidates based on costs associated with the plurality of candidates associated with candidate reference blocks. The cost of each candidate may be based on comparisons between a template of a current block and templates of the candidate reference blocks, where the templates of the candidate reference blocks have a shape flipped relative to that of the current block.
