TSL color space

TSL is a color space due to harv|Terrillon|Akamatsu|2000 that is used in face detection and based on tint, saturation and luminance.

The transformation from RGB to TSL is:

$S\; =\; sqrt\{frac\{9\}\{5\}left(\; r\text{'}^2\; +\; g\text{'}^2\; ight)\}$

$L\; =\; 0.299R\; +\; 0.587G\; +\; 0.114B$

where:

$r\text{'}\; =\; r\; -\; frac\{1\}\{3\}$

$g\text{'}\; =\; g\; -\; frac\{1\}\{3\}$

$r\; =\; frac\{R\}\{R+G+B\}$

$g\; =\; frac\{G\}\{R+G+B\}$
