Technology Review reports [Free reg. required] on a new intelligent image compression technology being developed (and available for licensing) by Xerox.
“Xerox is licensing its core technology for the Mixed-Raster Content Imaging model (MRC). The MRC imaging model is a central component of current and emerging standards for the communication of rasterized documents: ITU T.44 (MRC), T.37 (Internet Fax), JPEG2000, and JBIG2. The MRC imaging model represents a document as three "layers": a Foreground plane, a Mask plane and a Background plane. By distributing the image content according to type across these three layers, we can optimally represent a rasterized document.”
More information on how it actually works, can be found here.
