Image computing for visual information systems
Ishwar K. Sethi · 2002
The last few years have seen a remarkable growth of information in digital form due to a combination of several technological factors that include the availability of high speed electronic networks and affordable yet powerful desktop computing. This coupled with advances in scientific and consumer imaging technology-digital radiography, digital still cameras, desktop scanners, video capture boards, has created an environment where a large fraction of digital information is being created and disseminated in visual form-graphics, images, and video. This trend towards information in visual form is not surprising considering that we use vision more than any other sense to acquire and communicate information.>
