Abstract

The invention discloses a video coding method and a video coding device. The video coding method comprises the following steps of diving a macro block needing to be coded into 16 4*4 blocks, calculating boundary strength between two optional 4*4 blocks, determining a macro block dividing mode for the macro block according to the calculated boundary strength, dividing the macro block according to the determined macro block dividing mode, and coding divided sub blocks.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a video encoding method and system. Background technique [0002] At present, basically all video coding standards use a macroblock as a basic unit to realize the processing of a video frame. In currently widely used video coding standards such as H.264 and AVS, the coding process for the entire macroblock is generally implemented by dividing the macroblock into multiple sub-blocks and encoding the multiple sub-blocks respectively. A 16×16 macroblock (MB) can be divided into several sub-blocks. Such as figure 1 As shown, the macroblock partition mode includes 16×16, 16×8, 8×16, and 8×8 modes; and for an 8×8 block, it can be further divided into 8×4, 4×8, and 4×4 blocks . That is, the sub-division modes of the 8x8 block include 8x8, 8x4, 4x8, and 4x4 modes. Most video coding standards support intra-frame coding and inter-frame coding for blocks of various sizes, and mu...
