OpenCV applications deal with digital images and videos. OpenCV has been helpful in developing applications for fields like industrial automation, robotics, security, medicine, and transport. The developers can process images and videos using the cross-platform library. Image processing becomes faster in OpenCV as the machine language can be directly executed without performing interpretation. One can perform complex math on images with C and offer speed to applications.

OpenCV is supported by various programming languages like C++, Java, and Python. Moreover, OpenCV works on almost all platforms like Linux, Windows, OS X, Android, iOS, and others.
