Histogram Specification MCQs : This section focuses on the "Histogram Specification". These Multiple Choice Questions (MCQs) should be practiced to improve the Histogram Specification skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
Question 1

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
Question 2
For a local enhancement using mean and variance, there is one condition:
A. Enhancement is being done on light areas
B. Enhancement is being done on dark areas
C. Enhancement is being done independent of value of k0
D. None of the mentioned
Question 3
For a local enhancement using mean and variance, what happens if the lowest value of contrast is not restricted as per the willingness of acceptance of value?
A. There wouldn’t be any enhancement
B. Enhancement will occur for areas with standard deviation value > 1
C. Enhancement of the constant areas will also be the part of procedure
D. Enhancement will occur for areas with standard deviation value > 0 and < 1
Question 4
