Facial Recognition

Facial recognition is a technology that uses biometric software to identify or verify a person’s identity by analyzing their facial features. This process involves capturing the image of a face and comparing it against a database of known faces. Facial recognition systems typically use algorithms to detect key facial landmarks, such as the distance between the eyes, the shape of the jawline, and the contour of the cheekbones. This data is converted into a mathematical representation, known as a facial template, which is then compared with stored templates in a database to find a match. Facial recognition is used in various applications, including security, surveillance, law enforcement, and access control, as well as in consumer technology, such as unlocking smartphones and tagging individuals in photos on social media. The accuracy and ethical implications of facial recognition have been subjects of ongoing debate, especially related to privacy concerns and potential biases in the technology.
