Calculate a color value for the leafs. We can use known color spaces like CIELUV or CIELAB that separate the chroma and the intensity. We should also look into things like Green Chromatic Coordinate (gcc) or Excess Green (exg).

Calculate the amount of purple... What is purple? I think in order to detect amount of purple we need some example images of what is meant with purple.

This has been added. With respect to the purpleness of the image I have added the Hue component of the HSV color space as a feature. Purple are values that are close to 300.
