Question

If f(x, y) is a digital image, then x, y and amplitude values of f are

• A. Finite
• B. Infinite
• C. Neither finite nor infinite
• D. None of the above

Answer 1

Ans . A all should be finite!!

A image is a two-dimensional function f(x,y), where x and y are the spatial (plane) coordinates, and the amplitude of f at any pair of coordinates (x,y) is called the intensity of the image at that level.

an image to become digital, all x , y f should be FINITE

Answer 2

A digital image is a representation of a two-dimensional image as a finite set of digital values, called picture elements or pixels
