Hi! I'm trying to calculate the profile of a lens. I took the picture of the profile and now i'm trying to find the edge of the lens with a matlab code. I tryed to use edge detection algorithm but the problem is that the shades on the lens make it difficult.
I attach the picture
Does anybody can help me? Thank you in advance :)

Start your own discussion, and attach your image, at least the best image you can capture.

I'd say put more work into getting a better photo such as having a darker background, more "edge on" viewing angle, darker base that it's laying on, etc. Then it would be a lot easier and could be automated. For now, I'd suggest you use imfreehand() to hand-trace the lens. Let me know if you want a demo of imfreehand().
