Following method is used for face recognition using Artificial Intelligence:-
This approach utilizes global information from faces to perform face recognition. The global data(information) from faces fundamentally show by a small number of features which are directly derived from the pixel of face images. These small numbers of features distinctly capture the variance among different person faces and therefore are used to uniquely identify the person.
It is used in both holistic and local features. The concept of eigenfaces can be extended to eigen features, such as eigen eyes, eigen mouth, eigen noise, etc. Since most feature extraction methods have no special requirement on the input feature, it is reasonable to combine it with feature design procedure in order to seek more effective face representation.
