Finding watershed lines

[Martin Ichilevici de Oliveira]

Hello,

I'm trying to find watershed lines of an image. I tried using
mahotas.cwatershed, but all tutorials I found for it are just interested in
labeling regions. Also, I'm unsure which markers to use.

Any help is appreciated. Thank you.

mahotas.cwatershed has a return_lines parameter you can use for this:

It depends on what you want to do, of course.

A typical choice is to the regional minima (which can be obtained using
mahotas.regmin)

It also exist in SimpleCV and is pretty straight forward to use:

from SimpleCV import Image
img = Image('your_img_here.jpg')
watershedimg = img.watershed()
watershedimg.show()
