基于屏幕内容的视频编码块划分优化算法
Optimization algorithm for video coding block partitioning based on screen content
近年来，随着高清视频和超高清视频的出现，在线视频流媒体服务的广泛普及，以及
对视频会议需求爆发式增长，屏幕视频压缩算法的研究受到广泛的关注。块划分作为传统视频编码的第一环节决定了后续编码的质量，但是块划分环节存在大量的无效递归计算，本文提出使用决策树模型快速决策当前待编码块的划分方式，选用合适的屏幕内容视频块特征，最终有效提升块划分阶段的效率，有效提升了屏幕内容视频编码的速度。

In recent years, with the emergence of high-definition and ultra high definition videos, the widespread popularity of online video streaming services, and the explosive growth in demand for video conferencing, research on screen video compression algorithms has received widespread attention. As the first step in traditional video encoding, block partitioning determines the quality of subsequent encoding. However, there are a large number of invalid recursive calculations in the block partitioning process. This paper proposes using a decision tree model to quickly determine the partitioning method of the current block to be encoded, select appropriate screen content video block features, and ultimately effectively improve the efficiency of the block partitioning stage and the speed of screen content video encoding.
