摘要

为了防止丢包，提出了一种新的修正的多描述SPIHT编码。该方法根据人眼感兴趣的区域，对小波零树进行重新排序，并对冗余树赋予不同的编码速率。仿真结果表明，在丢包情况下，与其他多重描述编码方法相比，该方法在客观上和主观上都能提高图像质量。

A new robust multiple description coding method based on region of interest

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.
