Paper Abstract

The optoelectronic pattern recognition processor has to deal with scenes including various backgrounds. The background around the target may change the correlation peak value and can lead to false alarms. In this paper phase encoded input scenes with non-overlapping uniform background have been analyzed. The phase-only filter matched to a phase encoded target and the phase version of a minimum-mean-square-error filter, have been applied during the recognition procedure. Digital and optical results obtained for various input scenes have shown that in the case of a high level of non- overlapping input background the introduction of phase encoding scenes can significantly improve the recognition results.
