Real-time face detection

Real-time face detection is a technology that allows computers to quickly identify and locate human faces within live images or videos, such as from a camera feed. Using advanced algorithms, it analyzes visual data frame-by-frame to find facial features like eyes, nose, and mouth, often irrespective of lighting or angle. This process happens almost instantly, enabling applications like security, facial recognition, or augmented reality to respond instantly. Essentially, it's the computer’s way of “seeing” and recognizing faces in real-time, facilitating interactive and automated systems in various fields.
