BACIC: a new method for lossless bi-level and grayscale image compression
M.D. Reavy, Charles Boncelet · 2002
BACIC is a new method of lossless bi-level image compression introduced to replace JBIG and G3, the current standards for bi-level and facsimile image compression. This paper applies the BACIC (block arithmetic coding for image compression) algorithm to reduced grayscale and full grayscale image compression. BACIC's compressed files are slightly smaller than JBIGs, twice as small as G3s, and at least thirty percent smaller than lossless-JPEGs (when lossless JPEG uses Huffman coding) for reduced grayscale images with fewer than 7 bits/pixel.
