Recently face recognition is attracting a lot of attention in society access to multimedia network information. Such as network security, content indexing and video recovery and compression benefits from face recognition technology because people are the focus of many video. control through facial recognition not only makes hackers virtually impossible to steal your "password", but also increases ease of use in the human-computer interaction.
A training set consists of facial images from which a set of eigen faces can be generated by performing a mathematical process called Principal Component Analysis (PCA) on a large set of images representing different human faces. new faces can project a new image (mean subtracted) on the eigenfaces and thus record how that new face differs from the middle face
The eigenvalues associated with each eigenface represent how much the images in the training set vary from the average image in that direction. We lose information by projecting the image into the subset of the eigenvectors, but we minimize this loss by keeping those eigen faces with the larger eigen values.
