Description: Making spectral measurements with colors like red, green and blue, and grays, can be done with digital image analysis tools. Measurement of color is a newly emerging tool and can be accomplished with accuracy and reliability with this image analysis program. Pixels or picture elements are the smallest units of a digital image containing color information.
