Hello, I need some suggestion about image processing to know whether it can be done using C /c++ as I am not familiar with MATLAB. I have attached one image. The arrow in the image show the indented circlular portion. I need to crop out only the portion inside the indented portion. I think there should be a sharp difference in gradient intensity in pixel at the indented portion. Is it possible to extract that portion out by reading the binary image?

Thanks in advance.
