Patricia Donovan, the GIS lab manager at the Blacksburg campus, selected all the very small RGB values from image statistics and captured all the green vegetation. Using tools in the ArcMap software, it is possible to select out only pixels that meet the criteria RGB values <= 0.105 which returns the actual number of pixels. Now it is possible to calculate green vs non-green vegetation, soil, etc.
I am trying to figure out a bare bones way of doing this that can be used as a Photoshop macro. Hopefully we will have something to measure against SamplePoint's results before the end of Winter.
