Question

Assume that an image f(x, y) is sampled so that the result has M rows and N columns. If the values of the coordinates at the origin are (x, y) = (0, 0), then the notation (0, 1) is used to signify :

(a) Second sample along first row

(b) First sample along second row

(c) First sample along first row

(d) Second sample along second row

I have been asked this question in my homework.

I'm obligated to ask this question of Representing Digital Images in chapter Digital Image Fundamentals of Digital Image Processing

Answer 1

Correct choice is (a) Second sample along first row

To explain I would say: The values of the coordinates at the origin are (x, y) = (0, 0). Then, the next coordinate values (second sample) along the first row of the image are represented as (x, y) = (0, 1).
