Cartesian Perceptual Compression
TECHNICAL INFORMATION

Cartesian Perceptual Compression (CPC) is a novel image compression method specifically designed for document image storage and transmission systems. Designed by Cartesian Products, Inc., a high-technology research and development company based in Cambridge, Massachusetts, Cartesian's compression technology is the state of the art in document image compression methods, providing an order of magnitude better compression or more than other document image compression methods.

The CPC compression method is incorporated into CPC Lite, CPC View and CPC Tool, document imaging software available from this web site.

Companies interested in licensing the technology can contact us by email, post, phone, or fax.
