What Is Digital Image Processing? ¡ A sample digital image. 662*640*2 56. y x What Is Digital Image Processing? ¡ A sample digital image. 662*640*2 56. y x

f(x, y): A two-dimensional function, where x and y are spatial coordinates, and the f(x, y): A two-dimensional function, where x and y are spatial coordinates, and the amplitude of f at any pair of coordinates (x, y) is called the intensity or gray level of the image at that point. ¡ x size: 662, y size: 640, gray levels: 256 ¡ Digital image: x, y, and the amplitude values of f are all finite, discrete quantities ¡
