Skin probability look-up table obtained from the Bayesian classifier trained using the files in the train set list. Each line was created using: printf("%d\t%d\t%d\t%f\n", red, green, blue, probability); where red/green/blue are in [0;63] (the number of histogram bins per channel was reduced to 64), and the probability is in [0;1]. If a value does not appear, then its skin probability is 0.
