Abstract

The normalization of the correlation filter response effects intensity invariance. We discuss the implications of a normalization based on the Cauchy–Schwarz inequality for the discrimination problem. It is shown that normalized phase-only and synthetic discriminant functions do not provide the discrimination/recognition obtained with the classical matched filter.
