WebThresholding is the way of selecting areas of interest of an image while ignoring the parts we are not concerned with. It is most commonly used for background and foreground separation. We’ll also understand how to add a border around an image using the built-in function, copyMakeBorder () provided by the OpenCV library. http://amroamroamro.github.io/mexopencv/opencv/thresholding_demo.html
