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.
