First of all, the basic concepts of electronic images are given. The input devices (scanners and cameras) for different types of images are reviewed. Image storage, especially optical disks, is studied. Image computing including digital image processing, computer graphics, image pattern recognition and computer vision, visualization, and virtual realities are shortly covered. Image transmission facilities as well as image output devices are studied. Image retrieval methods together with hypertext and hypermedia systems are presented. Finally, some examples of image database systems are given. (Copyright (c) Valtion teknillinen tutkimuskeskus (VTT) 1990.) 收起
