63 This method will :
64
65 - copy the pixel values from the response to the volume image
66 - compute the maximum and minimum value while discarding the
67 outliersHalfRejectionRate_ fraction of the outliers from both the start
68 and the end of the distribution.
69
70 In English, this means that, if the volume dataset contains a few extreme
71 values very different from the rest (outliers) that we want to get rid of,
72 this method allows to do so.
73
74 If you supply 0.005, for instance, it means 1% of the extreme values will
75 be rejected (0.5% on each side of the distribution)
