Questions tagged [face-recognition]

Face recognition is the process of matching faces to determine if the person shown in one image is the same as the person shown in another image. This is distinct from face detection which only determines where an image exists a face. Face recognition has broad use in security technology, social networking, cameras, etc.

Face recognition is the process of matching faces to determine if the person shown in one image is the same as the person shown in another image. This is distinct from face detection which only determines where in an image exists a face. Face recognition is part of a larger class of biometric technologies.

There are two main modes of face recognition, one to one (where two faces are compared to each other) and one to many (where one face is matched against many faces). There are a number of free and open source and commercial face recognition tools and libraries. Face recognition is built into cameras, social networking sites (like Facebook), photo sharing sites (like PicasaWeb), and smart phones (like modern iPhone and Android phones).
