Face Swap is a digital technique that allows users to exchange faces between two or more people in a photo or video. This is often done using software or apps that utilize artificial intelligence to detect facial features and seamlessly blend them onto another person's face. The result can be humorous or surreal, making it popular for social media sharing. The technology behind Face Swap can also be used in various fields, including film and video game production, where it helps create realistic character animations. However, it raises ethical concerns regarding privacy and consent, especially when used without permission.
