Experiments on Biometric Comparators

Abstract

Experiments with respect to advanced comparators discussed in Chap.9 are conducted in this chapter, employing a common evaluation protocol and setup. Investigated issues comprise the accuracy of each comparator, computational requirements compared to the baseline technique using HD with applied bit-shifting to account for rotational alignment, as well as related questions. More specifically, the distribution of reliable bits or trade-offs between recognition accuracy and speed is evaluated.
