A Comparison between Quaternion Euclidean Product Distance and Cauchy Schwartz Inequality Distance - Advances in Computational Science and Engineering - page 137

4Conluon
This paper mainly proposes a comparison by two different discriminate dis-
tance, Quaternion Euclidean Product Distance (QEPD) and Cauchy-Schwartz
Inequality Distance (CSID), in order to solve space incompatibleness and curse
of dimensionality in a non-subspace means. Here we call palmprint or finger
texture biometric traits as ”handmetric”. From the experiments, we can safely
provide two conclusions: (1) the algorithm of QEPD is better than that of CSID,
(2) finger texture, this novel biometric is a better discriminative than traditional
biometric palmprint for QEPD or CSID.
