Abstract
3-D embedded wavelet video coding (3-D EWVC) algorithms become a vital scheme for state-of-the-art scalable video coding. A major objective in a progressive transmission scheme is to select the most important information which yields the largest distortion reduction to be transmitted first, so traditional 3-D EWVC algorithms scan coefficients according to bit-plane order. To significant bit information of the same bit-plane, however, these algorithms neglect the different effect of coefficients in different subbands to distortion. In this paper, we analyze different effect of significant information bits of the same bit-plane in different subbands to distortion and propose a high-efficient significant coefficient scanning algorithm. Experimental results of 3-D SPIHT and 3-D SPECK show that high-efficient significant coefficient scanning algorithm can improve traditional 3-D EWVC algorithms' ability of compression, and make reconstructed videos have higher PSNR and better visual effects in the same bit rate compared to original significant coefficient scanning algorithms respectively.
