Hi,
I have boundaries of semi-circle or eclipse shaped objects. Example images are
The boundary are not smooth and often slightly jagged (when you zoom in). I am looking to detect a point of interest (location x and y) on these boundaries, where we see a definite change in the shape, such as
There can be two outputs:
- No point of interest as we cannot find a definite change
- Point of interest with x and y location
Currently, I am using Python and OpenCV. I cannot think of an effective and efficient way to solve this problem
Any guidance in this regard will be really appreciated
