Image normalization
The following dialog allows you to normalize the current image according to the specified mean and standard deviation (std) of pixel values. The mean and std of the current image before the normalization are computed and displayed initially.
The following example shows an image before and after an increase of std value (similar to an increase of contrast).
The original image (mean=72.6, std=64.1):
After normalization (mean=72.6, std=128):
