| 摘 要： | 根据质量可伸缩视频编码（SVC）的特征,提出一种适合于粗粒度质量SVC增强层的帧间快速编码算法。首先,根据基本层宏块的模式和率失真值,预测当前宏块编码模式采用的顺序;然后,根据残差系数的分布特征提出了残差系数判断,根据空间相关性提出了率失真值判断;最后,根据模式已预测的顺序编码当前宏块,利用残差系数判断和率失真值判断进...

| Abstract: | Based on the characteristics of quality scalable video coding(SVC),a fast inter encoding algorithm is proposed for the enhancement layer of coarse grain quality scalability(CGS).Firstly,according to the base layer macroblock mode and rate-distortion,the order of the current macroblock coding mode was proposed,and then based on the residual coefficients distribution,the spatial correlation,the residual coefficients,and rate distortion decisions were proposed,respectively.Finally,the macroblocks w... |
