... equivalent to the original- order method for larger values of N. 4. Face Recognition Using Spectral Eigenfaces We showed in Section 3 that multiband eigenface methods can improve face recognition ... independently. A more general approach is to consider the full spectral/spatial structure of the data. One way to do this is to apply the eigenface method to large composite images...
