WebErosion removes small-scale details from a binary image but simultaneously reduces the size of regions of interest, too. By subtracting the eroded image from the original image, boundaries of each region can be found: b = f − (f s ) where f is an image of the regions, s is a 3×3 structuring element, and b is an image of the region boundaries.
