Introduction 1. What is a Digital Image An image can be defined as a two-dimensional function f(x,y), where x and y are spatial (plane) coordinates, and the amplitude of f at any coordinate (x,y) is referred to as the brightness or grayscale of the image at that point. When the values of x, y, and … Read more
