DjVu: Document Image Compression

DjVu is the ultimate in document image compression.  Back in 1995, when working on my thesis, I noticed how some types of color images could be compressed many orders of magnitude more if the sharp edges like text where compressed bitonally.  Like many other people, I noted it as a curiosity and then shoved it aside to continue my current research.

One person, Yann Lecun, realized the significance of the observation.  DjVu was born thanks to the efforts of Leon Bottou, Yann LeCun, Patrick Haffner, Paul Howard, and Yoshua Bengio, with some contributions from Pascal Vincent, Patrice Simard, and Steven Pigeon.  My involvement with DjVu began in 1998 as lead developer, and continued even after DjVu was sold by AT&T Labs to LizardTech Inc.  Today, I still provide consulting services to LizardTech Inc. in their DjVu products.

Enough of my ramblings, how about some interesting DjVu links:
