TRANSFORM-BASED IMAGE CODING METHOD AND DEVICE THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18529817 titled 'TRANSFORM-BASED IMAGE CODING METHOD AND DEVICE THEREFOR
Simplified Explanation
The image decoding method described in the abstract involves performing inverse first-order transform and inverse non-separable transform on a residual sample, based on transform index and multiple transform selection (MTS) index.
- Inverse first-order transform and inverse non-separable transform are performed on a residual sample.
- The inverse non-separable transform is based on a transform index indicating a predetermined transform kernel matrix.
- The inverse first-order transform is based on a MTS index indicating MTS for horizontal and vertical transform kernels.
- Syntax element bin string for the transform index is derived based on first or second context information depending on the tree type for a split structure of a target block.

Original Abstract Submitted
An image decoding method according to the present document comprises a step for performing inverse first-order transform and inverse non-separable transform on a residual sample. The inverse non-separable transform is performed on the basis of a transform index indicating a predetermined transform kernel matrix, the inverse first-order transform is performed on the basis of a multiple transform selection (MTS) index indicating MTS for a horizontal transform kernel and a vertical transform kernel, and a syntax element bin string for the transform index is derived on the basis of first context information when a tree type for a split structure of a target block is not a single tree type and is derived on the basis of second context information when the tree type is the single tree type.
