Abstract
We investigate the effect of the pre-processing stage parameters on performance of a smart card face verification system (SCFVS). We show that their optimal choice can improve not only the system accuracy but also the speed of verification. Some unexpected behaviour in the system performance is explained by a frequency space analysis of the effect of preprocessing. The analysis further leads to the broadening of the scope of parameter optimisation with beneficial results.
