Hi, to eliminate the intersected point. But this is not the important part. I want to know if there is a way to detect self intersected contour

The contour is the outside border of your polygon. So it won't have any intersections - even if the polygon has self intersections.

Perhaps you can work with cv::isContourConvex() though the function output is undefined for intersected contours.

contours are polygons. you'll find more material when you search for that instead.
