Abstract: Multiple Description image Coding （MDC） is a new method which can effectively improve the data receival quality in the irresponsible networks.Combined with the coefficients distribution characteristic of DCT subdomain in JPEG coding and the existing MDBDS algorithm，the paper presents a 4-descriptions image MDC algorithm based on coefficients radial segmentation in DCT subdomain.With the repeating distribution of DC coefficients and putting zeros to the absent AC coefficients，the method gets nice description reconstruction effects.Experiment results prove its general feasibilities are better than the MDEZW and MDBDS algorithms at the same compressed rate.
