I need to detect the different shapes on the image such as ellipses and circles with a dashed-border.
Using OpenCV causes some troubles, for e.g. openCV detects not a contour but an amount of small separated lines(contours).
In case of ellipse with a "dashed-border" I need it to be as single contour, not a separated objects.
What would you suggest to solve this problem?
I also need to recognize the ellipses(or circles) with solid border and ellipses(circles) with a dashed-border
Ellipse with solid border
Ellipse with dashed border:
The Hough transform should not have any troubles with either dashed or solid borders, or a mix thereof. I have used it to detect dashed lines in one of my project and ellipses should not be much harder.
