Abstract

A fast lossless compression scheme is proposed here. It consists of two stages. In the first stage, a Differential Pulse Code Modulation (DPCM) is used to decorrelate the raw image data for increasing the compressibility of medical images. In the second stage, an effective scheme based on the Huffman coding method is developed to encode the residual image. This newly proposed method could reduce the cost for the Huffman coding table while achieving high compression ratio. With this algorithm, a compression ratio higher than that of lossless JPEG method can be obtained. At the same time, this method is quicker than the lossless JPEG2000.Hence it provides a good means for lossless medical image compression.
