Abstract
Computer vision is an interdisciplinary field that deals with how computers can be made to gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to automate tasks that the human visual system can do. As a scientific discipline, computer vision is about the theory behind artificial systems that extracts information from images. With the emergence of big vision data and the development of artificial intelligence, it is important to investigate new theories, methods, and applications in computer vision.
