Abstract

This letter presents a new tiling scheme to achieve multiresolution and subregion image access as well as progressive retrieval, such as drill-down browsing and remote zooming/panning. This new scheme is based on the standard JPEG2000 algorithm. While JPEG2000 only divides the original image into tiles, the presented scheme divides each coarse version of the image into equal-sized tiles and reorders the wavelet coefficients in each of the steps of the analysis process. This new scheme avoids the problems associated with the traditional tiling, as used in JPEG2000, getting better lossy and lossless compression ratios, reducing disk or network latency, and improving the quality of the image
