Hi, I am trying to get a circular ROI within the image. For rectangular ROI we can use imrect and get the position/coordinate, so is there a similar function to take circular ROI ?. I tried with imellipse but the coordinate that the function return I am not able to crop using imcrop. I am attaching an image here with desire ROI please let me know your suggestions. Thank you,
