Cartesian Products, Inc. is a high-technology research and
development company based in Newton, Massachusetts. The company
was founded in September 1991 to provide advanced software technology
to improve worldwide communication and information access.
Cartesian Perceptual Compression (CPC), the company's first
invention, is an efficient method for compressing document images.
The invention regularly compresses document images an order of
magnitude better than industry-standard compression methods. Such
dramatic compression opens up whole new application areas for document
images by allowing storage of full images in about the space required
previously for the textual information alone.
The invention has especially far-reaching implications for the
Internet, fax, and document image management industries. Internet and
intranet distribution of document images becomes practical with the
reduced storage requirements and download times provided by CPC. For
the fax industry, the compression method can cut fax transmission
time, thereby significantly reducing telephone charges while improving
resolution. For the document image management industry, the method
can cut storage requirements dramatically, thereby allowing for lower
hardware costs, faster image retrieval, and better performance.
Cartesian Products has been granted a United States patent on its
technology and has applied for patent protection abroad.
