\section{Introduction}
% The very first letter is a 2 line initial drop letter followed
% by the rest of the first word in caps.
% 
% form to use if the first word consists of a single letter:
% \IEEEPARstart{A}{demo} file is ....
% 
% form to use if you need the single drop letter followed by
% normal text (unknown if ever used by the IEEE):
% \IEEEPARstart{A}{}demo file is ....
% 
% Some journals put the first two words in caps:
% \IEEEPARstart{T}{his demo} file is ....
% 
% Here we have the typical use of a "T" for an initial drop letter
% and "HIS" in caps to complete the first word.
\IEEEPARstart{F}{or} the assignment of Introduction to Biometrics an analysis needs to be done on Verilook and the Face REcognition Grand Challenge (FRGC) database. Where Verilook is state of the art face recognition software and the FRGC database consists of 50,000 recordings. The Verilook system will generate matching scores between two pictures from the FRGC database. The verification performance is usually abstracted from a single ROC. It is possible though to test this performance on a individual ROC\rq{}s. Which gives the possibility to find cases and/or individuals for which the verification performance drops.
