-#NRMSE a normalization of the root of the mean squared error
-#NRMSE is simply 1 - [RMSE / (maxval - minval)]. Where maxval is the maximum
-# intensity from the two images being compared, and respectively the same for
-# minval. RMSE is given by the square root of MSE: 
-# sqrt[(sum(A - B) ** 2) / |A|],
-# where |A| means the number of elements in A. By doing this, the maximum value
-# given by RMSE is maxval.
