Perception, analysis , and identification by a functional unit of one or more constituent objects within an image . Image recognition may include scene analysis . The process by which a degraded image is returned to its original condition.
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.
