| 摘 要： | 基于立体视频数据压缩的目的,提出了一种基于残差宏块自适应下采样立体图像编码方案。该方案采用H.264标准,独立编码左通道参考图像。应用视差估计和运动估计联合补偿技术编码右通道目标图像,在目标图像的编码过程中,根据目标图像运动场景的不同,对图像残差块进行选择性的下采样编码。与原始的JMVM算法相比,在相同的峰值性噪比下,该算法具有更高的编码效率。

| Abstract: | For the purpose of compressing the stereo video data,this paper proposes an algorithm for stereo image coding based on adaptive down-sample method for residual macroblock reisdual-downsampled of macroblock.A stereo image pair consists of a reference image and a target image.The left channel reference image sequence is coded by method using H.264 standard,while the right channel target image sequence is coded by using disparity estimation and motion estimation joint compensation prediction technique.During t... |
