Multiple Description Image Coding Based on DSC and Pixel Interleaving
This paper presents a novel multiple description image coding (MDC) using the theory of distributed source coding (DSC). The scheme is based on pixel interleaving MD image framework. A so-called Slepian-Wolf set partitioning in hierarchical tree (SW-SPIHT) is presented to efficiently and flexibly insert redundancy in each description and help to estimate the lost description. Experiments demonstrate that it can get better performance than some general MDC methods. Besides, it demonstrates higher robustness in packet-loss channel than pixel interleaving MDC method due to the error-correcting decoding adopted by DSC.
