1.	The spatial coordinates of a digital image (x,y) are proportional to:(a) Position(b) Brightness(c) Contrast(d) NoiseThe question was posed to me at a job interview.This key question is from Introduction to Digital Image Processing topic in portion Basic of Digital Image Processing of Digital Image Processing
Answer» RIGHT option is (B) Brightness To explain I would say: The Brightness levels are DISTRIBUTED over the spatial area. HENCE, the spatial coordinates are proportional to brightness levels.
