This module contains functions for simple histogram manipulation. Use this to scale the image for viewing or to perform simple light-level normalization accross multiple images.
Adjust the image histogram to have fixed mean and standard deviation. This can be used for simple light level normalization.
Perform logarithmic compression on the image. This will enhance dark features and suppress bright features. Use this to visualize images with high dynamic range. (FFT results, for example)
Histogram stretch scales the image to fit the range [0,1]
