| 摘 要： | 提出了一种基于光学子波变换的综合判别函数匹配滤波器(WFSDF),将光学子波变换和综合判别函数相结合,只用一个简单的4f系统就能实现输入图像和SDF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,与传统的SDF匹配滤波器相比,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,能够实现多目标的畸不变识别。

| Abstract: | Based on optical wavelet transform,a new SDF matching filter(WFSDF) was proposed.This filter has not only the property of optical wavelet but also that of SDF.The correlation between the wavelet transforms of input images and SDF can be realized in one simple 4f system 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,simply the optical device and realize the rotation and scale invariant optical correlation pattern recognition of multiple-target. |
