Best Answer

What do you need? You could possibly get overall mean intensity or color, LAB or HSV color, area, perimeter, standard deviation, skew, kurtosis, uniformity (entropy), area fraction of blood vessels, number of spots/defects, etc. Plus there's all those things that regionprops measures that I didn't even mention.
