An image may be defined as a 2-dimensional function f(x, y) where x and y are ________ and the amplitude of the function is called ________ of the image at the point (x, y)
Show answerHide answer
Correct answer: (C) Coordinates; intensity
Explanation
In f(x, y), x and y are spatial coordinates, and the amplitude of f at any point is the intensity (grey level) of the image there.
