摘要： An image processing system processes tiles in a predefined order (168). A wavelet transform uses short filters applied to image boundaries to generate edge coefficients. Long filters are used to image data at interior locations to generate non-edge coefficients (172). Both filters are applied only to image data within the title and only to transform coefficients within the earlier sets of transformed data. A corresponding decoder is provided at the client (180).
