Advanced technology: Digital image processing: Images that provide both high resolution and large dynamic range are transmitted, stored, and processed by digital means

Digital image processing is helping the U.S. Department of Defense solve problems involving invisible, infrared, synthetic aperture radar, and cartographic data. NASA is applying the technology in remote sensing. Medical applications center on ultrasound and computer-aided tomography. Legal uses involve fingerprints and graphic evidence. Graphics-arts applications include photo composition and four-color printing. And communications uses are in optical character recognition and electronic mail.
