            **What it does**

            MeasureImageIntensity measures several intensity features across an entire image (excluding masked pixels).
            For example, this module will sum all pixel values to measure the total image intensity. You can choose to measure all pixels in the image or restrict the measurement to pixels within objects that were identified in a prior module. If the image has a mask, only unmasked pixels will be measured.
            Note that for publication purposes, the units of intensity from microscopy images are usually described as “Intensity units” or “Arbitrary intensity units” because microscopes are not calibrated to an absolute scale. Also, it is important to note whether you are reporting the mean vs. the integrated intensity, so specify “Mean intensity units” or “Integrated intensity units” accordingly.
            Keep in mind that the default behavior in CellProfiler is to rescale the image intensity from 0 to 1 by dividing all pixels in the image by the maximum possible intensity value. This “maximum possible” value is defined by the “Set intensity range from” setting in NamesAndTypes; see the help for that setting for more details.
