Document Type and Number:
WIPO Patent Application WO/2022/063033
Kind Code:
A1
Abstract:
A video decoding method and apparatus, a video coding method and apparatus, a computer-readable medium, and an electronic device. The video decoding method comprises: performing entropy decoding processing on a coded block of a video image frame to obtain a quantization coefficient block of residual data corresponding to the coded block; respectively performing statistical processing on quantization coefficients in a plurality of areas in the quantization coefficient block to obtain a statistical result of each area in the plurality of areas, and determining the remainder of the statistical result of each area relative to a set value; according to the remainder of each area, selecting a transform matrix combination corresponding to the coded block; and on the basis of the selected transform matrix combination, performing inverse transform processing on an inverse quantization result of the quantization coefficient block.
