SegmentationLevelSetFunction is a subclass of the generic LevelSetFunction.

It useful for segmentations based on intensity values in an image. It works by constructing a speed term (feature image) with positive values inside an intensity window (between a low and high threshold) and negative values outside that intensity window. The evolving level set front will lock onto regions that are at the edges of the intensity window.

Image is thresholded pixel by pixel using threshold according to the following formula.
