Indices

Nr.	Name	General Formula	Comment
1	Coloration Index	$\frac{RED - BLUE}{RED}$
2	Hue	$\arctan (\frac{2 R - G - B}{30.5} (G - B))$
3	Intensity	$(\frac{1}{30.5}) (R + G + B)$
4	Normalized Difference NIR/Red	$\frac{NIR - RED}{NIR + RED}$
5	Normalized Difference Red/Green	$\frac{R - G}{R + G}$
6	Saturation	$\frac{\max (R, G, B) - \min (R, G, B)}{\max (R, G, B)}$
7	Shape Index	$\frac{2 R - G - B}{G - B}$
