Optimization of Binary Phase Only Filter with Simulated Annealing Algorithm
Myung Soo Kim, Michael R. Feldman, Clark C. Guest · 1989
Binary phase only filters (BPOF) show excellent performance for matched filtering. However, when the BPOF is synthesized to distinguish similar patterns, existing encoding methods do not produce good results because the binary state of each pixel on the filter is not optimally encoded. In this paper we examine an optimum encoding of the BPOF for matched filtering to distinguish similar patterns, using a simulated annealing algorithm (1).
