CONTEXT MODEL SELECTION METHOD AND APPARATUS, DEVICE AND STORAGE MEDIUM

摘要

Disclosed are a context model selection method and apparatus, a device, and a storage medium, belonging to the technical field of audio and video. The method comprises: determining a reference coding unit of a target coding unit; according to the reference coding unit, predicting a block division structure of the target coding unit to obtain a predicted block division structure of the target coding unit; and on the basis of the predicted block division structure of the target coding unit, determining a context model respectively used by at least one syntax element involved in the block division of the target coding unit. In the present application, a selection condition of a context model is optimized, so that the entropy coding efficiency is improved, the number of bits of a code stream is reduced, and the video compression efficiency is improved.
