Face recognition system with database

% FACE RECOGNITION BASED ON HIERARCHICAL DIMENSIONALITY REDUCTION
%
%
% Copy all files in Matlab current directory and type "hdrface" on
% Matlab command window.
%
% First, select an input image clicking on "Select image".
% Then you can
%   - add this image to database (click on "Add selected image to database"
%   - perform face recognition (click on "Face Recognition" button)
%     Note: If you want to perform face recognition database has to include
%     at least one image.
%  If you choose to add image to database, a positive integer (face ID) is
%  required. This posivive integer is a progressive number which identifies
%  a person (each person corresponds to a class).
% For example:
%  - run the GUI (type "hdrface" on Matlab command window)
%  - delete database (click on "Delete Database")
%  - add "mike1.jpg" to database ---> the ID has to be 1 since Mike is the first
%    person you are adding to database
%  - add "mike2.jpg" to database ---> the ID has to be 1 since you have already
%    added a Mike's image to database
%  - add "paul1.jpg" to database ---> the ID has to be 2 since Paul is the second person
%    you are adding to database
%  - add "cindy1.jpg" to database ---> the ID has to be 3 since Cindy is
%    the third person you are adding to database
%  - add "paul2.jpg" to database ---> the ID has to be 2 once again since
%    you have already added Paul to database
%
% ... and so on! Very simple, isnt't? :)
%
% The recognition gives as results the ID of nearest person present in
% database. For example if you select image "paul3.jpg" the ID given SHOULD
% be 2: "it should be" because errors are possible.

% 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.
%
% Face Recognition:                              face matching. The selected input image is processed
%
% Delete Database:                               remove database from the current directory
%
% Info:                                          show informations about this software
