利用记录介质的非线性实现相关峰的锐化
Correlation peak sharpenness by using nonlinearity of recording medium
摘要
本文提出一种在光学相关识别中改善相关峰锐度的方法.在制作匹配滤波器时利用记录介质的非线性突出输入图像的边缘,从而实现了相关峰的锐化.文中详述了该方法的实现过程及理论基础,并给出了光学实验和计算机模拟实验的结果.
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.
