Hello, I had a similar problem: [image: contour02.png] I tried to resolve the problem this way <https://dip4fish.blogspot.com/2012/10/contour-looking-for-negatively-curved....> using polygonal approximation. The result will depend on the scale of resolution I guess. Jean-Patrick Le mer. 8 mai 2019 à 10:37, Stefanie Lück <luecks@gmail.com> a écrit :
Hi everybody,
I am working on a computer vision problem but I got stuck. I am trying to detect outer points of an binary image (see attached images, points which i need are labeled in red on image points.png).
I have tried different approaches (edges, maximas, corner detection) but usually the inner corners will be detected because the outer points I need are rather round.
Any idea of an algorithm which might be useful for this problem?
Thanks a lot in advance, Stefanie
