Spiht and odd-even estimation based MDC algorithm

Based on the SPIHT compression method, this paper proposes a new Multiple Deseription Coding (MDC) algorithm with the simple odd-even estimation idea. We divide the original image into two parts called the odd and even parts, and then compute the difference between them as the residual part. Based on these three parts, we construct a multiple description encoder with three channels. The successful application of the reshaped redundancy gets high compression efficiency and keeps the structure character of the original image. To evaluate the performance, we apply our method to image communication. We compare our algorithm with several traditional methods under the assumption that there is at least one channel that can always be trusted. Experimental results demonstrate the effectiveness of the proposed method.
