| 摘 要： | 提出一种用非相干光系统识别彩色图像的方法，将脸色图像分解成三个单色像处理，设计一可实现的仅相位光学传递函数，对其进行带能优化，人而提高信噪比并使相关峰锐化，通过一对滤波器来合成该光学传递函数，获得了采色图像相关识别的实验结果。

| Abstract: | A method of recognition of color image under incoherent optical system is proposed. A color image is decomposed 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. The experimental results on color image recognition are presented. |
