Ignoring the medical and psychological aspects, i see this topic as an interesting debate about computer vision and artificial intelligence:
1) the computer vision can give answers on how human subjectivity
can alter even the simplest decision processes ( an algorithm or a reference system created by human can be affected by uncertainty due to its subjectivity )
2) it is an evidence of the importance of fuzzy modeling also in the simplest decision logics
3) considering the histogram of the image colors , the technique of histogram specification applied to other photos could alter the perception of other ones and get similar results from the people
What do you think about?
