Histogram Equalization in FingerCrop not working properly

Tried to run baseline fingervein experiments with Histogram Equalization post-processing as part of the FingerCrop pre-processor. The arrays in "extracted" directory contain all 0s (but they should be binary) and the score file containonly "nan"s. The issue seems to be that the pre-processed data are in the range (0, 1) whereas the binarization threshold is based on the original image range of (0, 255).
