摘要：

A novel lossless image-compression scheme is proposed in this paper. A two-stage structure is embedded in this scheme. A linear predictor is used to decorrelate the raw image data in the first stage. Then in the second stage, an effective scheme based on the Huffman coding method is developed to encode the residual image. This newly proposed scheme could reduce the cost for the Huffman coding table while achieving high compression ratio. With this algorithm, a compression ratio higher than that of the Lossless JPEG method for 512 x 512 images can be obtained. In other words, the newly proposed algorithm provides a good means for lossless image compression. (C) 2000 Elsevier Science B.V. All rights reserved.
