Motivation behind the denormalize function

[deepakdilipkumar]

The denormalize function in layers.py is defined as (layer + 1.)/2. If the aim is to revert the earlier normalization, shouldn't we have (layer + 1.)*127.5?

Asking because I'm facing a problem where the refined images are extremely dark (low intensity), since the pixel values are very low after denormalization.
