1994.12.14 22:00 "JBIG compression", by Kyriakos Georgiou
Is there anybody that is working on JBIG compression/decompression ? (besides Image Magic, MA USA) Also, can the current libtiff G4 decompression implementation be improved ? What sort of improvements can be expected ? I was surprised to find a reference to J.D.Murray, W.vanRyper, "Encyclopedia of Graphics File Formats", O'Reilly & Associates, Inc. 1994, pp.148 which stated that some implementations of G4 encode as fast as G3, and decode even faster. I don't want to get into algorithmic issues, my question is, is there room for >15% improvement on G4 for the impelmentation of libtiff ? K.Georgiou RIT Research Corp.
