Question

For a local enhancement using mean and variance, there is one condition: ms(x, y) ≤ k0 MG, where, MG is global mean, k0 a constant and ms(x, y) a measure of gray value as light or dark at point (x, y). Then, which fact is true for k0?

a. It is a negative constant with values less than -1.0

b. It is a positive constant with values less than 1.0

c. It is an integer constant with values between -1.0 and 1.0

d. None of the mentioned

Answer 1

Correct option is (b) It is a positive constant with values less than 1.0

To elaborate: In the condition ms(x, y) ≤ k0 MG, k0 is a positive constants whose value is always less than 1.0.
