Abstract

The circular harmonic function (CHF) correlation filter originally proposed by Hsu and Arsenault uses only one harmonic of the reference image and thus ignores much of the discriminatory information contained in the reference image. Various methods have been proposed to make use of multiple harmonics. In this work, we present a method that combines three useful objectives: using multiple circular harmonics, controlling the correlation response to in-plane rotation and minimizing the correlation plane energy in order to achieve sharp correlation peaks. Basic theory underlying this method as well as some simulation results are presented. The implications of dealing with spatially discretized images on the interpretation of CHF coefficients also is discussed.
