| 摘 要： | 本文提出了一种用非相干系统识别采色图像的方法，将彩色图像分成三个单色像处理，设计一可实现的仅位相型光学传递函数（ＯＴＦ），对其进行带通优化，从而提高信噪比并使相关峰锐化，通过一对滤波器的来合成该ＯＴＦ。介绍了滤波器制作原理和方法，获得了彩色图像相关识别的实验结果。

| Abstract: | In this paper,we proposed a method of recognition of color image under incoherent light. A color image is divided into three monochromatic images to be processed,then a realizable phase-only optical transfer function(OTF) is designed. The passband of this OTF is optimized to increase the signal to noise ratio(SNR) and to yield a sharp correlation peak.This OTF can be synthesized by a couple of filters,and the method to produce the filters is given in detail. The experiment on color image recognition is carried out and has confirmed our proposed theory. |
