Color model based on a lookup table.
Very fast and easy implementation of a lookup table. It ignores the luminance and determines the classification just based on the U and V chrominance values. This model is very versatile as you can generate the lookuptable with many different methods.

Determine classification of YUV pixel.
Given a pixel in the YUV colorspace the colormodel determines the color classification based on some a-priori knowledge.
y | Y value |
u | U value |
v | V value |
