I have an application where I am interested in looking at the uniformity in an image by colouring regions that fall into various bins. I have included an example with a raw image, an image where there is a different colour from -5% to 5% in 1% increments, and an image where there is a different colour from -10% to 10% in 2% increments. In this case they are all taken as deviations from the mean.
I am relatively new to ImageJ, but I have done a little bit of scripting and I believe that this application will require something custom. I would like to be able to define the nominal as either the mean or a known value. I would also like to be able to choose different bin widths (as in the example), such as every 1%, 5%, 10%.
