Computing Threshold

At this time the only threshold method is Otsu’s method. The following image is from the WikiPedia page (link). This object implements the Otsu thresholding method and returns it as a parameter in the group. The way you use this in a thresholding method, either to create a mask or a polygon is to import the group as a local variable (drag the group onto the + button) and then use the name of the parameter – otsu – as the threshold variable.
