Any one of a group of operations that improve the detectability of the targets or categories, such as contrast improvement, edge enhancement, spatial filtering, noise suppression, image smoothing, and image sharpening.
Any one of a group of operations which improves the interpretability of an image or the detectability of targets or categories in the image. These operations include contrast enhancement, edge enhancement, spatial filtering, image smoothing, and image sharpening.
Modification of the pixels of an image to improve its appearance. Common enhancement methods are smoothing, sharpening, histogram modification, and filtering.
Any process which increases the image definition by improving contrast and/or definition or reducing noise. When accomplished by computer programmes, it is referred to as digital image processing.
A procedure for manipulating the signal to sharpen or otherwise improve the image.
The process of improving or altering the appearance of an image, usually to assist the operator with feature extraction.
A signal processing technique to sharpen or improve the image.
