OpenCV
OpenCV is a popular toolkit that helps computers understand and work with images and videos. Think of it as a set of ready-to-use tools that developers use to make machines "see" and understand visual information. It's commonly used in robotics, self-driving cars, security systems, and smartphone apps that use cameras. When you see job descriptions mentioning OpenCV, it usually means the role involves working with cameras, image processing, or creating systems that can automatically recognize objects, faces, or movements in images or video feeds.
