FACE RECOGNITION SYSTEM
 
  Face recognition system based on EigenFaces Method.
  The system functions by projecting face images onto a feature space
  that spans the significant variations among known face images. The
  significant features are known as "eigenfaces" because they are the
  eigenvectors (principal components) of the set of faces.
 
  Face images must be collected into sets: every set (or class) should
  include a number of images for each person, with some variations in 
  expression and in the lighting. When a new input image is read and added
  to the training database, the number of class is required. We choose a
  number of eigenvectors M' equal to the number of class (see algorithmic
  details in the cited references).
 
  The images included are taken from AT&T Laboratories Cambridge's
  DataBase. See the cited references for more informations.
  
  
  FUNCTIONS
 
  Select image:                   read the input image
 
  Add selected image to database: the input image is added to database and will be used for training
 
  Database Info:                  show informations about the images present in database. Images must 
                                  have the same size. If this is not true you have to resize them.
 
  Face Recognition:               face matching. The selected input image is processed 
 
  Delete Database:                remove database from the current directory
 
  Info:                           show informations about this software
 
  Exit:                           quit program
