Macroscopic multistage image compression for robust transmission over noisy channels
Greg Sherwood, K. Zeger · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
We propose a macroscopic multistage compression system to provide progressive and robust transmission of images across noisy channels with varying statistics. Each stage encodes the residual image of the previous stage. The choice of source coder and transmission rate at each stage are design parameters. The multistage structure allows the use of efficient unequal error protection channel coding and introduces source redundancy to enable graceful degradation under severe channel conditions. Both bit errors and packet losses are considered. Specific examples are provided to demonstrate the performance of the proposed method.
