'''Stages:'''

1. Getting started with OpenCV
  * tutorial [http://www.cognotics.com/opencv/servo_2007_series/index.html]
  * examples[[BR]]
    * [http://www.cognotics.com/opencv/downloads/camshift_wrapper/index.html]
    * fixed bugs in these examples in order to run them.
 
2. Selection of Face Recognition algorithms
  * PCA (Principal component analysis) [[BR]]
       * Jacobi method was choosen for generating eigenvectors.[[BR]]
       * [http://www.cs.otago.ac.nz/cosc453/student_tutorials/principal_components.pdf Brief tutorial ]
  * ICA (Independent Component Analysis)[[BR]]
    [http://ieeexplore.ieee.org/search/wrapper.jsp?arnumber=1058079]

3. Implementation
  * face detection and image manipulation using OpenCV functions.
  * serial and parallel implementation for PCA using C, OpenCV and OpenMP. 
  * serial and parallel implementation for ICA using Matlab and C wrappers.
     * starting point for ICA's serial code : http://mplab.ucsd.edu/~marni/code.html
  * login module:
     * modified the original gdm (Gnome) login screen.
     * used [http://www.gstreamer.net/ GStreamer ] with webcam source and a normal video sink. 
     * the webcam image is output in a GTK widget.
     * GTK window used as wrapper for an X window.
