| 摘 要： | 提出了一种基于光学子波变换自聚焦综合判别函数(WFSDF)匹配滤波器。这种匹配滤波器,将光学子波变换和综合判别函数(SDF)相结合,只用一个傅里叶变换透镜就能实现输入图像和SDF的子波变换的相关运算。采用计算全息的方法制作复数匹配滤波器。计算机模拟仿真结果表明,和传统的SDF匹配滤波相关器相比,WFSDF匹配滤波器锐化了相关峰,提高了识别率,同时简化了光路。

| Abstract: | A new self-focusing SDF Matching Filter based on optical wavelet transform(WFSDF) is proposed in this paper.This filter not only has the property of optical wavelet but of SDF.The correlation between the wavelet transforms of input image and SDF can be realized with only one Fourier transform lens by use of WFSDF.The WFSDF can be fabricated by computer generated hologram.Computer simulation results indicate that WFSDF can sharpen correlation peak,improve the efficiency of correlation recognition,simplify the optical device and can realize the rotation and scale invariant optical correlation pattern recognition of multiple-target. |
