Cartesian Perceptual Compression

Cartesian Perceptual Compression (CPC) is emerging as an alternative to CCITT Group 4 compression as it provides higher compression ratios for storing 1-bit TIFF images for faster downloads and smaller storage requirements.

The reduction in document size provided by CPC compression permits us to offer the highest level of service to our clients, and the system of visualization is perfect.
Rubén Sánchez Peña, DIVULNET s.l.
This dramatic reduction in file size could enable an entirely new breed of imaging applications, due to the commensurate reductions in transmission costs, download times, and publication costs.
Ira Fuchs, Chief Scientist of JSTOR, Inc.

The Cartesian Perceptual Compression (CPC) format was developed in the early 1990's in response to bandwidth limitations that were preventing the introduction of network-based electronic libraries. By using adaptive perceptual filters based on the dynamics of the human visual system, the CPC algorithm is able to reduce images to as much as 1/30th the size of the corresponding TIFF files -- with no loss in image fidelity. In fact, in blind tests of subjective image quality run by the International Organization for Standardization (ISO), subjects actually preferred CPC compressed images over the original images.

CPC Tool and the CPC format are currently in use in a variety of products and services, encompassing a broad range of applications including Internet fax services, document distribution, educational assistance, and electronic libraries.
