What condition prevents the intensity artifacts to be created while processing with contrast stretching, if r and s are gray-values of image before and after processing respectively?
A. r1 = s1 and r2 = s2
B. r1 = r2, s1 = 0 and s2 = L – 1, L is the max gray value allowed
C. r1 = 1 and r2 = 0
D. r1 ≤ r2 and s1 ≤ s2
