New Methods for Lossless Image Compression Using Arithmetic Coding.
Peer reviewed Peer reviewed
Howard, Paul G.; Vitter, Jeffrey Scott – Information Processing and Management, 1992
Identifies four components of a good predictive lossless image compression method: (1) pixel sequence, (2) image modeling and prediction, (3) error modeling, and (4) error coding. Highlights include Laplace distribution and a comparison of the multilevel progressive method for image coding with the prediction by partial precision matching method.…

Models of Bitmap Generation: A Systematic Approach to Bitmap Compression.
Peer reviewed Peer reviewed
Bookstein, Abraham; Klein, Shmuel T. – Information Processing and Management, 1992
Presents new methods for compressing bit matrices in large information retrieval systems which exploit possible correlations between rows of words and columns of documents. Three encoding methods are tested and compared--Shannon-Fano, arithmetic, and Huffman--and an appendix discusses binomial coefficients. (20 references) (LRW)
