In Windows 10 and Windows 11, the Microsoft Photos app uses face detection and facial grouping technologies to help you quickly and easily identify and organize photos of friends and family. Face detection distinguishes faces from other objects in an image. For example, face detection helps the Photos app know when there is a face in a photo or video so that the app can further analyze the photo. Facial grouping identifies and groups similar faces across multiple photos or videos in your personal collection.
