Dear ImageJ community,


Can anyone give me the details of how the Gaussian noise is calculated with 'Process > Noise > Add Specified Noise...'? Can anyone reference a paper or give me the basic principle?


I'm asking because I want to add Gaussian noise to an array of numbers. I would prefer not to export my data to another platform e.g. Excel or R. If I know the details of how the Gaussian noise is added in an image then I could have a go at writing an algorithm that will do this to an array of numbers. Failing that, I suppose I could do the reverse and turn my array of numbers into an image - then use 'Process > Noise > Add Specified Noise...'.


I welcome your thoughts or comments,


Thanks,


Greg.
