| Abstract: | A correlation peak sharpening method in optical pattern recognition is proposed in this paper. The edge enhancement of input images was obtained by using nonlinearity of recording medium, hence the correlation peak was sharpened. The procedure and theoretic basis are presented in detail with both optical experiment and computer simulation results. |

| Keywords: | optical recognition nonlinearity correlation peak sharpness matched filter |
