Abstract Video coding based on 3D wavelet transform draws more and more attention. However, it is necessary to improve its coding efficiency. Based on the analysis of the 3D wavelet transform coefficients distribution characteristics of video and unavailability of zerotree coding in temporal high-frequency frames, the zerocube model of temporal high-frequency frames and the 3D wavelet video coding algorithm based on octcube split are proposed in this paper. In this algorithm, low-frequency subbands and high-frequency subbands obtained by 3D wavelet transform are processed respectively, the zerotree structure of set partitioning in Hierarchical tree (SPIHT) is adopted for the former, the zerocube structure of octcube split is utilized for the latter. Since the 3D transform wavelet coefficients are organized together by zerocube structure, the synchronous information of lonely zero coding is reduced. Meanwhile, a coefficient is coded only when it is significant. Thus, to scan insignificant coefficients repeatedly is avoided. Experimental results show that for various standard test video sequences, the proposed algorithm has good reconstruction quality.
