To classify the inspection area as accepted or rejected the histogram tool evaluates
two different magnitudes within the specified region:
Mean defines the min and max value for the inspection model. If the inspection
area has a mean value less than min or higher than max the inspection area will
be classified as rejected.
Std dev is a statistical measure that illustrates how closely all the various pixel
values are clustered around the mean value. An even color tone gives a narrow
histogram with low standard deviation while a speckled pattern gives a wide
histogram and a high value for Std dev.

The Mean and standard deviation parameters can be selected for the target
