"WebbThresholding. #. Thresholding is a technique of image segmentation. It separates a given single-channel image (or stack) into two regions: Pixels with intensity below a given threshold, also called “background” and pixels with intensity above a given threshold, “foreground”. Typically those algorithms result in binary images where ... " - Simpleitk otsuthreshold
