摘要：
In this paper, a new multiple description coding (MDC) method for color images is presented. The proposed approach bases on the set partitioning in hierarchical trees (SPIHT) algorithm to achieve a high image compression ratio; employs poly-phase sampling technique to generate multiple descriptions to adapt to varying internet environments. It results in having capabilities to conquer packet losses and remaining the reconstructed images with an acceptable quality. In order to preserve the progressive reconstruction properties for a color image transmission, the three components (Red, Green, and Blue) are encoded separately and their encoding results are interleaved for transmission. The proposed method is applicable to color images and is very flexible for practical applications. The experimental results are given to illustrate the characteristics and verify the efficiency of the proposed method.
