A method and interface for finding image intensities of an image on a
computing device is provided. Finding these image intensities includes
displaying an image on a display device having a range of intensities,
identifying one or more regions of the image according to the intensity
values in each of the one or more regions, categorizing each region as
falling into one intensity zone category from a set of intensity zone
categories according to the intensity value for each region and
displaying the image on the display device with the regions and
corresponding related intensity zone categories highlighted.
