Abstract :
A virtual SPIHT (VSPIHT) technique that is based on the SPIHT and virtual zero-tree concepts is proposed. It combines virtually generated zero trees on the top of SPIHT´s zero trees to reduce the effective number of zero trees. The simulation results show that the proposed video coder is more efficient compared to SPIHT based video coders, particularly at very low bit rates
