Abstract
We extend our previous paper, where the focus was on error-resilient zerotree wavelet image coding on noisy channels. This concept is extended to video coding using a 3-D wavelet transform. The proposed video coding system consists primarily of a 3-D wavelet transform, coding via the 3-D set-partitioning in hierarchical trees (SPIHT) algorithm, and bit partitioning followed by bit reorganization procedure. Simulation results show that the proposed coders outperform the existing error-resilient coders from the standpoint of both noise-free channels and noisy channels. In addition, we confirm that the proposed algorithm is more error-resilient than the conventional 3-D zerotree wavelet video coding techniques for various channel-error conditions as evidenced by both objective and subjective evaluations.
