71. 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

72. For a local enhancement using mean and variance, there is one condition: σs(x, y) ≤ k2DG, where, MDG is global standard deviation, k2 a positive constant, and σs(x, y) a measure of contrast at point (x, y). Then, which fact is true for k2 if its value is less than 1.0?

A. Enhancement is being done in light areas

B. Enhancement is being done in dark areas

C. Enhancement is being done independently of the value of k0

D. None of the mentioned
