<title>Optical laboratory implementation of advanced detection and distortion-invariant filters</title>

Abstract

This paper presents optical laboratory data on a number of new optical filter systems for: rank-order morphological filtering, morphological ternary phase amplitude filters, morphological hit-miss detection filters, Gabor detection filters and distortion-invariant detection filters. All filters and processing are performed on the same optical correlator architecture. This provides a general purpose multi-functional optical image processor for general scene analysis, capable of low-level vision, detection, and image enhancement operations.

“…This is the solution h = Mw in (3) that satisfies the correlation peak constraints +() = U (5) and minimizes the objective functions Ec wMDN (6) ---C--------EN MPNu(M). (7) This solution is obtained by Lagrange multiplier techniques.…”

“…The Gabor clutter map filter portion of it is detailed elsewhere [5]. Hardware realization of all filters has been addressed with laboratory data [6,7] and the use of binary and ternary phase filters has been noted.…”
