Abstract

As a high efficiency video coding (HEVC) extension, screen content coding (SCC) has a significant effect in the compressed screen content, but causes a problem encoder calculates a higher complexity. This paper proposes a fast decision method based on HEVC screen content coding. The image content is divided into a natural coding unit (NCU) and a screen coding unit (SCU). The image gradients of different properties are different, and the gini impurity classification gradient value is used to speed up the encoding speed. The experimental results show that under the frame configuration of HM-15.0 SCM-2.0, the method can save about 41.4% of the encoder time.

HEVC屏幕内容编码的快速算法

屏幕内容编码(SCC)作为一种高效的视频编码(HEVC)扩展，在压缩屏幕内容方面效果显著，但造成编码器计算复杂度较高的问题。提出了一种基于HEVC屏幕内容编码的快速决策方法。图像内容分为自然编码单元(NCU)和屏幕编码单元(SCU)。不同属性的图像梯度不同，采用基尼杂质分类梯度值来加快编码速度。实验结果表明，在HM-15.0 SCM-2.0帧配置下，该方法可节省约41.4%的编码器时间。
