image sharpening is an operation of

the first step in digital image processing is

the process that assigns a label
to an object based on the information provided
by its descriptors

assigning meaning to an
ensemble of recognized objects

extracted data should be represented

Improving appearance of
an image. Tend to be based on mathematical or
probabilistic models of image degradation
