Facial recognition technology is a tool that helps computers identify and recognize people by looking at their faces. It’s like when you see a friend and know who they are just by looking at them. This technology does the same thing but uses cameras and special programs to make it happen. It’s becoming very common in places like phones, stores, and even airports.
How Facial Recognition Works
Facial recognition follows a few basic steps to recognize someone’s face.
Collecting Facial Images
First, the system takes a picture of your face. This can be done through your phone’s camera, a security camera, or any device with a camera.
Analyzing Facial Features
Next, the system studies the image. It looks at things like the distance between your eyes, the shape of your nose, and the curve of your jawline. Think of it like a puzzle where every face has its own special pieces.
Matching Against Stored Data
Finally, the system tries to match your face with images it already knows. If there’s a match, the system recognizes you. If not, it might ask for more information.
