@Steve This is what I get on MMA 10.4 in the case of the square domain you suggested; I guess WatershedComponents has been modified / upgraded since version 9. Unfortunately I don't have access to version 9 to test further.

Yeah, without running the ContourPlot, it can't remove the frame. Nonetheless, it's still not working for me after fixing that bt replacing the CirclePoints problem by just making it a square for now, and get i.imgur.com/vxQIzWO.png

@Steve That doesn't look right. The outputs I get from the code are shown in my answer, and they are definitely different. It almost looks like the frame was still present when the image was fed into WatershedComponents. Can you run Show[contour, Frame -> False] on its own and check that the frame / axes are correctly removed?

| Apr 18, 2016 at 16:07 | comment | added | Steve | Yes, I'll expand on that. Also, this is what it's doing for me on the other contours: i.imgur.com/OrCQaG7.png | |

@Steve I added the output of my CirclePoints expression, so you can test it on v.9. Also, I wanted to try this method out on your contours, put I couldn't immediately find where that contour plot you show was generated in the question you linked. Could you expand on that in your question?

Added CirclePoints workaround

Hmm. So I can't directly test your solution in version 9.0 because of CirclePoints, and so far my attempts at applying your solution directly to my image have been unsuccessful.

What are you saving as variable "contour"?
