Automatic identification technology research on Opto-electronic hybrid pattern recognition system

Abstract

Opto-electronic hybrid optical pattern recognition technology has many advantages, but must to recognize the correlation-peak from lots of noise. This paper analyzes the deference of correlation-peak image and the noise, and researches on the contour distribution of the image of the correlation-peak and the noise. So, bring forward using the BP network of the ANN to distinguish the signal and noise automatically. The experiment results show the effectiveness of the method.
