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.
