- A Convex object is one with no interior angles greater than 180 degrees.
- Hull means the exterior or the shape of the object.
- Hence, onvex Hull of a shape or a group of points is a tight fitting convex boundary around the points or the shape.
- We can find convex hull in opencv by firstly making the image binary and finding the contours in the image.
- Convex hull in OpenCV can be obatined with the help of the following method
cv2.convexHull()
Here blue lines show the convex hull for the yellow contours
