I have a raster which have NaN values. I would like to evaluate graythresh for my data, but the NaN values are taken into account and as a results I have 0 (zero). Is there a way to exclude NaN values from evaluation or remove them from data?

What is EM, the effectiveness metric output? Otsu is not great for all images, it's really only for when there is an object in the foreground.
