Abstract
The present application relates to the technical field of video decoding. Provided in the embodiments of the present application are a video image decoding method and coding method, an apparatus, and a storage medium, which help to improving the image quality. The method comprises: acquiring channel-level complexity levels from a data stream, the data stream being a coding data stream of a current block; according to at least two channel-level complexity levels, determining the block-level complexity level of the current block, the channel-level complexity levels being used for representing the complexity degree of the channel-level texture of the current block; according to a code control parameter, determining a target bit number of the current block, the code control parameter comprising the block-level complexity level of the current block; on the basis of the target bit number, determining a quantization parameter of the current block; and on the basis of the quantization parameter, decoding the current block.
