When an image is mostly composed of background pixels, most of the automatic thresholding methods are failing to produce a relevant threshold. This is mainly caused because one mode is over represented compared to the other in the histogram of the image. The Kappa-Sigma clipping, a method largely used in astronomy, don’t try to separate 2 modes in the histogram, but rather try to find the properties of the only usable mode, the one of the background, and compute a threshold to select the values significantly different of the background.
