Top Hat
The Top Hat module performs an erosion (shrinks the current white image), followed
by a dilation routine (grows the current white image) and then subtracts the original image. Erosian
followed by dilation will open closed objects. Subtracting the original
will result in the display of just the pixels that close the object.
Interface
Instructions
1. Specify the number of times to perform erosian before dilation. Higher numbers will
open thicker connected objects which will result in larger connections being displayed
in the final image.
