Application of Case-based Teaching in Computer Vision with OpenCV and Python

— In recent years, with the rapid development of big data and artificial intelligence, computer vision technology has been employed in the process of the development of the computer, and also has a certain application in mechanized production. In this paper, the overviews of OpenCV and Python are presented. Additionally, image processing methods are introduced, such as image enhancement and restoration, image edge sharpening, image segmentation and recognition, and image transformation. Finally, we introduce some applications of computer vision technology.
