This limits the application of such a system.
Once established, the eigenface method was expanded to include methods of preprocessing to improve accuracy.

In practical applications, most faces can typically be identified using a projection on between 100 and 150 eigenfaces, so that most of the 10,000 eigenvectors can be discarded.
The eigenfaces themselves form a basis set of all images used to construct the covariance matrix.Belhumeur, P N, and Hespanha, J,P, and Kriegman,.5.1.1980, wilmington, Delaware, USA, dominic West herec / reisér nar., sheffield, Yorkshire, Anglie, Velká Británie.Such gifts ensure that an area of our work that you are interested in will continue to thrive long into the future and enable us to continue to inspire our residents and visitors alike. .1947) Rasmus West (kameraman) Red West (herec, nar.Choose the principal components.1986) Jennessa West (producentka / hereka) Jennifer West (reisérka) Jim West (reisér) Joe West (herec) Jonathan West (kameraman / reisér / herec) Jouni West (reisér / scenárista / stiha, nar.
