Abstract
A two-stage lossless image compression scheme is presented, the first stage of which decorrelates the raw image data by using a two-dimensional, causal linear predictor, resulting in significant entropy reduction. The second stage uses standard coding techniques. Different two-stage schemes are compared with respect to their performances on several images, using bilevel coding, arithmetic coding, and adaptive Huffman coding
