TRANSFORM-BASED IMAGE CODING METHOD AND DEVICE FOR SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17773295 titled 'TRANSFORM-BASED IMAGE CODING METHOD AND DEVICE FOR SAME
Simplified Explanation
The image decoding method described in the abstract involves deriving residual samples and generating a reconstructed picture based on modified transform coefficients. The modified transform coefficients are derived by parsing an LFNST index and an LFNST matrix.

Original Abstract Submitted
An image decoding method according to the present disclosure comprises the steps of: deriving residual samples with respect to a target block on the basis of an inverse primary transform with respect to modified transform coefficients; and on the basis of the residual samples, generating a reconstructed picture, wherein a step of deriving the modified transform coefficients may include the steps of: parsing an LFNST index on the basis of the tree-type of a current block not being a dual-tree chroma and a MIP mode not being applicable to the current block; and deriving the modified transform coefficients on the basis of the LFNST index and an LFNST matrix.
