Presents a new image compression technique called “DjVu” that is specifically geared towards the compression of high-resolution, high-quality images of scanned documents in color. With DjVu, any screen connected to the Internet can access and display images of scanned pages while faithfully reproducing the font, color, drawings, pictures and paper texture. A typical magazine page in color at 300 dpi can be compressed down to between 40 to 60 KBytes, approximately 5 to 10 times better than JPEG for a similar level of subjective quality. Black-and-white documents are typically 15 to 30 KBytes at 300 dpi, or 4 to 8 times better than CCITT-G4. A real-time, memory-efficient version of the decoder was implemented, and is available as a plug-in for popular Web browsers
