| 摘 要： | 由于光学傅里叶变换过程中光的衍射作用,在光学相关识别中,输入图像的形状对称性会影响匹配滤波器的畸变容限和输出相关峰值。针对几种典型的匹配滤波器算法,定量分析了利用这些算法设计的匹配滤波器的畸变容限和输出相关峰值受输入图像形状对称性的影响程度,依此来比较这些算法的特性,并进行了模拟和实验。

| Abstract: | Due to diffraction of optical wave in the optics Fourier Transform,the shape symmetry of inputting image affects distortion tolerance of matched filter and outputting correlation peak value.The effecting input image's symmetry on the distortion tolerance of matched filters and output correlation peak values is analyzed quantitatively,which is designed by use of different matched filter arithmetic.The distinction of these arithmetic is compared,and simulation and test are made. |
