Progressive lossless compression of medical images

Abstract

This paper describes a lossless compression method for medical im-ages that produces an embedded bit-stream, allowing progressive lossy-to-lossless decoding with L-infinity oriented rate-distortion. The experimental results show that the proposed technique produces better average lossless compression results than several other com-pression methods, including JPEG2000, JPEG-LS and JBIG, in a publicly available medical image database containing images from several modalities.
