Grayscale generated from a Desaturate algorithm

A desaturated image. Desaturating an image takes advantage of the ability to treat the (R, G, B) colorspace as a 3-dimensional cube. Desaturation approximates a luminance value by choosing a corresponding point on the neutral axis of the cube for each pixel. (The actual formula is (max(R,G,B) + min(R, G, B)) / 2)
