Additional assignment (choose 2 of 4 at maximum):
    
1. [extra 5 points]
   Choose a threshold. Using this threshold, the demo application
   and the supplied set of facial images, prepare a list of matches
   (couple of images) which exceed the threshold,
   OR create the FAR/FRR and ROC graphs.

2. [extra 5 points]
   Play a bit with the verilook demo and prepare 2 images of your face
   that DO MATCH at the default threshold, but the images are very 
   different.

3. [extra 5 points]
   Play a bit with the verilook demo and prepare 2 images: one of anybody
   but not you and one of you so that the images DO MATCH at the default
   threshold.

4. [extra 5 points]
   Play a bit with the verilook demo. Use some of your older images and
   describe (1 page A4 incl. images) what images do match and what image do not match.
   (E.g. since 7 all my images match, younger photos cannot
    be recognized as me ...).
