DIP: Topic 4: What is a Digital image?
What is a Digital image? We usually operate on digital (discrete) images: Sample the 2D space on a regular grid. Quantize each sample (round to nearest integer. A digital image can be defined as a two dimensional function, f (i,j), where x and y are spatial coordinates, and f intensity or gray-level of the image at that point. A digital image is composed of a finite number of elements called pixels , each of which has a particular location and value.
