UNIT I DIGITAL IMAGE FUNDAMENTALS 1.1. Define Image. An Image may be defined as a two dimensional function f(x,y) where x & y are spatial (plane) coordinates, and the amplitude of f at any pair of coordinates (x,y) is called intensity or gray level of the image at that point. When x,y and the amplitude values of f are all finite, discrete quantities we call the image as Digital Image. 1.2. Define Image Sampling. Digitization of spatial coordinates (x,y) is called Image Samplin...
