Paper Abstract

A measure describing an overall estimate of the feasibility of correlation filters is introduced. Our feasibility estimate (FE) measure is based on the established filter criteria such as the noise tolerance, peak sharpness, and diffraction efficiency. These quantities are described using a functional scheme of a standard optical correlator system. A basic set of correlation filters is defined regarding the amplitude and phase information contents. To describe quantitatively the white noise case as well as the increase or decrease of the input scene power, a simple noise model is used. The usefulness of the FE concept is demonstrated on the filter parameter optimization problem and also by presenting the decision curves for finding the true-class correlation peak values as a function of the total input signal power.
