Optimum encoding of binary phase-only filters with a simulated annealing algorithm
Myung Soo Kim, Michael R. Feldman, Clark C. Guest · Optics Letters · 1989
A simulated annealing algorithm is introduced to encode binary phase-only filters optimally for image recognition. Similar patterns that cannot be distinguished with conventional filter encoding methods are clearly distinguished with the optimized filter. The computational requirements for optimizing the filter are not excessive.
