Investigation of High Efficiency Generalized Matched Filters.

Abstract

In a previous RADC contract Aerodyne worked on developing an improved algorithm for reducing the rotational dependency of matched filters for use in optical pattern recognition systems. This present contract takes the final result of that effort, the so-called Generalized Matched Filter (GMF), applies the phase-only filter principle to it, and studies the results. Standard actual noisy IR images are used so the result can be compared to other such studies. Also included in this report is a brief discussion of complexity theory and how it might apply to optical computing efforts in the U.S. and elsewhere. Keywords include: Correlation; Pattern recognition; Spatial filtering; and Phase-only filters.
