Hello,

I am trying to measure two different particles of a very similar brightness
and have been attempting to do so by subtracting a canny edge detection
image from the original image in order to create a white barrier between
the two particles. However, the edge detected by the canny edge detector
does not completely split the two regions. Is there any program I can run
which will automatically connect nearby lines? For my purposes I cannot use
manual tools such as the pencil.

I have attached an image of the region I am talking about (circled in red)
and an image of what I want the image to look like (drawn in blue).

Thank you,
James
