Video coding with virtual set partitioning in hierarchical tree

This paper proposes an efficient wavelet based video coding system using virtual set partitioning in hierarchical trees (VSPIHT). A novel composite spatial orientation tree (SOT) is proposed to extend the use of VSPIHT for color frames and the color VSPIHT (CVSPIHT) based hybrid video coder is proposed. The intra- and inter coding performance of the proposed coder is measured with that of H.263 based coder. The simulation results show that the proposed coder outperforms the H.263 based coder at very low bit rates, whereas H.263 performs better at higher bit rates.
