The binary step is no problem, the image is turned to binary anyhow.
the process itself is fine, it neatly closes the gap, but it also expands
the selected region. Also it requires some user input as the gaps aren't
always the same distance, for our research, it is important to get the
user input to a minimum (to minimize error)
anyway, this might solve some of the issues that I'm encountering ,
thank you for the help
