本文介绍一种基于结构分割的自适应编码系统。图像组（ＧＯＰ）中参考帧的数目以及它们间的间隔由可补偿性分析自适应地确定。时间视觉掩盖效应已利用于合理分配不同帧的码率。实验结果表明，这种自适应调整图像组结构的编码系统，无论视觉效果还是信噪比，都明显优于固定结构的编码系统。
This paper introduces a structure-based adaptive coding system. The number of reference frames in a group of pictures (GOPs) and the spacing between them are adaptively determined by the compensability analysis. Time visual masking effect has been used to rationally allocate different frame rate. The experimental results show that the coding system adaptively adjusting the structure of the image group is obviously superior to the fixed structure coding system, no matter the visual effect or the signal-to-noise ratio.
