Perfect reconstruction, quality scalability, and region-of-interest coding are basic features needed for the image compression schemes used in telemedicine applications. This paper proposes a new wavelet-based embedded compression technique that efficiently exploits the intraband dependencies and uses a quadtree-based approach to encode the significance maps. The algorithm produces a losslessly compressed embedded data stream, supports quality scalability, and permits regionof-interest coding.doi:10.1109/4233.788579 pmid:10719481 fatcat:cg3bws4sgjfxbpp63f3pqksf5q
