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) | |
