How eigenfaces work
Web3 aug. 2024 · Since EigenFaces also finds illumination as a useful component, it will find this variation very relevant for face recognition and may discard the features of the other people's faces, considering them less useful. In the end, the variance that EigenFaces has extracted represents just one individual's facial features. Web30 nov. 2024 · Face Recognition is one of the most popular and controversial tasks of computer vision. One of the most important milestones is achieved using This approach was first developed by Sirovich and Kirby in 1987 and first used by Turk and Alex Pentland in face classification in 1991. It is easy to implement and thus used in many early face ...
