In summary, with this book, we have made a step toward a better understanding of a computational theory of color constancy. The main question, which algorithm is used by the human vision system, however, is still unsolved. In the future, noninvasive techniques that help to visualize the workings of the human brain in combination with additional psychophysical experiments may one day lead to the actual algorithm used by the visual system.

So far, we have seen that given a neural architecture, the neural network may be trained to arrive at colors that are approximately constant. Evolution is also able to find a solution to the problem of color constancy. One of the remaining questions is about how a computational color constancy algorithm is actually mapped to the human visual system. Several researchers have looked at this problem and have proposed possible solutions. 

Figure 14.2 Likely description of the color constancy algorithm used by the human visual system to compute color constant descriptors. The parameter p is simply a small percentage as described in Section 10.2.
