One of the benefits of OpenCV is that it provides a number of built-in basic elements for image processing and computer vision related operations. If you need to write some content through scratch, you will have to define something, such as image, point, angle and so on. These are almost the foundation of any computer vision algorithm. OpenCV provides the basic data structures that are open and out of use, all of which are included in the core module. Another advantage is that these data structures have been optimized for speed and memory, so you don't have to worry about implementing the details.
