1.	Validate the statement:(a) , to sample the function we take equally spaced samples, superimposed on the function, along a horizontal line. However, the sample values still span (vertically) a continuous range of gray-level values. So, to convert the given function into a digital function, the gray-level values must be divided into various discrete levels.”(b) True(c) FalseI had been asked this question in homework.This intriguing question originated from Basics Of Image Sampling & Quantization topic in section Digital Image Fundamentals of Digital Image Processing
Answer» Right answer is (a) , to sample the function we take equally spaced samples, superimposed on the function, along a horizontal LINE. However, the sample VALUES still span (vertically) a continuous range of gray-level values. So, to convert the given function into a digital function, the gray-level values must be divided into various DISCRETE levels.” For EXPLANATION I would say: Digital function requires both sampling and quantization of the one-dimensional image function.
