Select these parameters to compute the intensity of the red 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 red will be measured in the calibrated engineering units.

RedAvrg returns the average red component of pixels within the object:
red1, where
N is number of pixels within the object

returns the standard deviation of the red 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
