Method and Apparatus of Video Coding Using Flexible Quadtree and Binary Tree Block Partitions

摘要

A method and apparatus for video coding using flexible quadtree and binary tree block partition are disclosed. According to this method, a current block is partitioned into multiple final sub-blocks using one or more stages of quadtree partitioning and binary tree partitioning, where at least one sub-block is generated by applying the quadtree partitioning to one previous sub-block generated by the binary tree partitioning. According to another method, one or more horizontal splitting flags and one or more vertical splitting flags are used for determining block partition of the current block into multiple sub-blocks using one or more stages of quadtree partitioning and binary tree partitioning. Multiple sub-blocks partitioned from the current block are determined according to the horizontal splitting flags and the vertical splitting flags. The multiple sub-blocks are then encoded or decoded.
