| 摘 要： | 传统的音视频编码标准(AVS)率失真优化(RDO)算法在帧间模式选择中使用偏差平方和(SSD)作为失真度量,不能很好符合人的主观视觉,而最近提出的结构相似度(SSIM)图像质量评价方法更符合人眼视觉系统(HVS)的特性.为了有效地提高编码效率,本文将SSIM引入拉格朗日代价函数,对失真度量的表示进行修正,并在大量实验的...

| Abstract: | The sum of squared differences(SSD) is used as the distortion metric for inter mode decision in traditional audio video coding standard(AVS) rate distortion optimization(RDO),but it is not consistent with human vision system(HVS) quite well after a lot of investigations.Compared with the other methods,the structural similarity(SSIM) proposed recently for assessing image quality accords with HVS much more well.Therefore,in order to improve coding efficiency,the SSIM is introduced into Lagrangian ... |
