Select these parameters to compute the intensity of the blue component within the objects on color images.

The intensity of pixels can optionally be scaled by using the Intensity calibration
. In this case all the intensity of Blue will be measured in the calibrated engineering units.

BlueAvrg returns the average blue component of pixels within the object:

blue1, where
N is number of pixels within the object

returns the standard deviation of the blue component within the object:


In the Field Measurements
the parameters are calculated for the whole phase rather than for separate objects.

For grayscale images both parameters are equivalent to GrayAvrg and GraySD
