What is FR?

FR, which most likely refers to Facial Recognition, is a technology that identifies or verifies a person from a digital image or a video frame from a video source. It works by analyzing and comparing facial features from the image with a database of known faces. Facial recognition is commonly used for security purposes, such as unlocking smartphones, surveillance, and access control. It is also used in social media for tagging people in photos, and in marketing for targeted advertising. However, its use raises concerns about privacy and potential biases.
