Abstract

Video processing methods and apparatuses for candidate set determination for a current block partitioned from a parent block by quad-tree splitting comprise receiving input data of a current block, determining a candidate set for the current block by prohibiting a spatial candidate derived from any of neighboring blocks partitioned from the same parent block or determining the candidate set for the current block by conducting a pruning process if all the neighboring blocks are coded in Inter prediction and motion information of the neighboring blocks are the same, and encoding or decoding thecurrent block based on the candidate set by selecting one final candidate from the candidate set. The pruning process comprises scanning the candidate set to determine if any candidate equals to the spatial candidate derived from the neighboring blocks, and removing the candidate equals to the spatial candidate from the candidate set.
