This method first estimates a cutoff, then calculates the distribution of pixels within the cutoff in order to determine the final threshold.

I have found this method to work quite well for fluorescence microscopy images in which most of the pixels are background and the background is approximately gaussian.

There are a couple parameters than can be used to tune the threshold.
