Abstract: A video coder without motion compensation based on 3D-SPECK was proposed. In order to carry out the three dimensional wavelet transform, the video sequences were partitioned into groups of frames (GOP), and the wavelet coefficients were organized as many wavelet cubes (WCs). The WCs were coded by the 3D-SPECK efficiently. The wavelet transform was carried out in the temporal axis instead of the traditional motion estimation/compensation, thus much computation was saved compared with the traditional hybrid coding model. Experiment results show that the proposed coding model achieves both measurable and subjective performances comparable with 3D-SPIHT.
