Simulated annealing algorithm for binary phase only filters in pattern classification.
A binary phase only filter is encoded with a simulated annealing algorithm to classify two similar characters in a variety of fonts. Characters that cannot be distinguished with conventional filter encoding methods are clearly distinguished with the optimized binary phase only filter using a simulated annealing algorithm. This method gives zero error classification rate for tested characters. Correlation performance of the optimized binary phase only filter is compared with the binary phase only filters encoded with conventional methods. The computational requirements for optimizing the filter are not excessive.
