A Study on Error Resilient Video Coding using 3D Wavelet Transform and its Error Concealment method

摘要

In this paper, we propose an error resilient and error concealment method for 3D wavelet video coding over wireless transmission. The proposed method consists of the following two schemes; the first one is a 3D wavelet encoding with dispersive grouping, and the second one is an estimation scheme for dispersive grouped elementary streams using a Minimum Mean Square Error (MMSE) algorithm at the decoder. Experimental results indicate that the proposed algorithm provides better performance from aspects of PSNR (Peak Signal-to-Noise Ratio) and visual quality.
