Abstract
The present application discloses a coding/decoding method and device, and a storage medium thereof, and belongs to the field of image processing technologies. The method includes: performing context-based adaptive binary arithmetic coding or context-based adaptive binary arithmetic decoding on first ISP indication information based on a context model in response to determining to code or decode the first ISP indication information, wherein the first ISP indication information is configured to indicate whether to enable an intra sub-block prediction mode; and performing bypass binary arithmetic coding or decoding on second ISP instruction information in response to determining to code or decode the second ISP indication information, wherein the second ISP indication information is configured to indicate a fashion of sub-block partition of the intra sub-block prediction mode. In this way, the number of context models required during a coding/decoding process can be reduced, the complexity of the coding/decoding process is reduced, and memory overheads are reduced.
