Image prediction machines and methods, and computer-readable storage media

Abstract

The term "creation" refers to machines and methods used to predict image patterns. The image prediction method includes the following steps: determine whether a merge mask is applicable to the current image block; if a merge mask is applied to the current image block, determine whether a level 1 merge mode is available for the current image block; If the first merging mode is unavailable, and the high-level syntax component corresponding to the first merging mode indicates that the first merging mode is disabled, directly identify the second merging mode as the target merging mode applicable to the current image block, where both the first and second merging modes belong to level 2 merging modes; and predict the current image block based on the target merging mode. According to the design options, the redundancy generated in the process of determining the optimal shade ratio can be reduced as much as possible.
