Barron & Torrent (1986) Redness Index in LAB color space
Description
Calculate Redness Index after Barron & Torrent (1986) "Use of the Kubelka—Munk Theory to Study the Influence of Iron Oxides on Soil Colour" using Munsell colors converted to LAB. DOI: 10.1111/j.1365-2389.1986.tb00382.x. Accepts vectorized inputs for hue, value and chroma, produces vector output.
Usage
barron.torrent.redness.LAB(hue, value, chroma)
Arguments
hue
A character vector containing Munsell hues (e.g. "7.5YR")
value
A numeric vector containing Munsell values
chroma
A numeric vector containing Munsell chromas
Value
A numeric vector of horizon redness index (higher values = redder).
