Image restoration is possible only to the extent that the degradation is mathematically invertible. An operation in which each pixel value of one image is subtracted from its corresponding pixel value in another image. A functional unit that generates a visual representation of objects by a computer without reference to real images . Any operation that produces an output image from an input image. In computer graphics , the movement of an image such that every point of the image moves parallel to and the same distance as every other point of the image.
Image translation is a nonrotational displacement of an image.
Electronic transfer of images from one point to another over a network . The comprehension of the significance of a scene . The output of image interpretation may serve as input to image understanding. The hardware and software designed specifically to capture, store , manipulate, transmit , and display images from either direct computation, real environments, models, or documents . A storage device whose access time is negligible in comparison with other operating times.
