Digital Image) An image can be defined as a two-dimensional function f (x, y). Here, X and Y are spatial coordinates, and in any coordinate (x, y) the amplitude F is called the brightness or gray scale of the image at the coordinate position. When the amplitude of X, Y, and F are finite discrete values, they are called digital images. Note that a digital image
