 '''
 Simple implementation of random contrast. This always switch half the time the polarity.
-then it decide of a bias and of a contrast, both of them are dependant of the complexity.
+then it decides of a random contrast dependant of the complexity, the mean of the maximum and minimum
+pixel value stays 0 (to avoid import bias change between exemples).
