On image insertion, I want the rgb value to be extracted (entire image is of one color) and then, concentration to be determined. Yes, I have a table correlating the RGB values to concentration. How do I proceed?

Attach your one-color (i.e., gray scale) image and your calibration table in a .mat file with the paper clip icon.
