摘要：

This paper describes a method that uses the well known S + P and TT transforms to encode a specially important part of an image, a region of interest (ROI) in a lossless mode. Other parts of the image (the background) are given lower quality levels allowing higher compression. The ROI coding is done in the framework of an embedded wavelet-based image compression algorithm. Entire coding, regional and full image, is done in a naturally progressive manner all the way up to lossless. (C) 1999 Elsevier Science B.V. All rights reserved.
