Abstract
A new revised multiple description SPIHT coding is proposed to combat packet loss. According to the region of interest of human eyes, the method reorders the zero trees of wavelets and assigns different coding rates to redundant trees. Simulation results show that the method can improve the image quality both objectively and subjectively compared to other multiple description coding methods in the case of packet loss.
