Menu:   Measure > Parameters  
Script:   SelectParam ("BlueAvrg", "BlueSD")  

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

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

blue2

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
