What is the main function of facial recognition technology?

1. Extracting text from images

2. Identifying individuals in images

3. Locating objects within images

4. Classifying images into categories

The correct answer is: Identifying individuals in images

The main function of facial recognition technology is to identify individuals in images. This technology utilizes various algorithms to detect human faces in photos or video streams and then compares the features of those faces against a database to determine the identity of the person. It relies on biometric recognition to accurately differentiate between various individuals based on unique facial characteristics such as the distance between eyes, the shape of the jawline, and other distinct features. Facial recognition has applications in numerous areas, including security systems, law enforcement, personal device authentication, and social media tagging, among others. The ability to reliably identify individuals quickly and effectively is what sets facial recognition apart from other imaging technologies. In contrast, the other options listed serve different purposes. Extracting text from images relates to optical character recognition (OCR), which is not concerned with identifying individuals. Locating objects within images deals with object detection, a task focused on identifying and classifying specific objects rather than identifying people. Classifying images into categories involves image classification techniques that categorize an image based on its content without necessarily identifying specific individuals. Therefore, identifying individuals is the distinct function that defines facial recognition technology.
