For this reason, it is essential to preserve the fidelity of individual components when considering methods of compression. Likewise the component level structure should be a prime consideration when ordering information for lossy or progressive transmission. We refine our work on document image compression as it applies to transmission and retrieval. We first overview the basic compression scheme, then describe a structural hierarchy which provides desirable properties for transmission. We present the results of a rate distortion experiment and discuss the implications for network applications JA - Multimedia Signal Processing, 1997., IEEE First Workshop on M3 - 10.1109/MMSP.1997.602657 ER -
