Abstract

In this paper, we compare the objective performance of several algorithms for coding motion compensated residuals, including the wavelet transform, matching pursuits and an improved embedded DCT-based coding method. A motion-compensated prediction-based approach with overlapped block matching compensation (OBMC) is used in all systems in the evaluation. The results show that matching pursuits outperforms transform-based methods by 0.1-1.0 dB in PSNR. The embedded DCT coder usually outperforms the wavelet-based SPIHT-AC in the examples considered, and SPIHT is usually better than JPEG 2000.

运动补偿视频中残余压缩方法的比较

在本文中，我们比较了几种运动补偿残差编码算法的客观性能，包括小波变换、匹配追踪和改进的嵌入式dct编码方法。在评估中，所有系统都采用了基于运动补偿预测的重叠块匹配补偿(OBMC)方法。结果表明，匹配追踪比基于变换的方法的PSNR提高了0.1 ~ 1.0 dB。在考虑的示例中，嵌入式DCT编码器通常优于基于小波的SPIHT- ac，并且SPIHT通常优于JPEG 2000。
