光学图像识别技术的MATLAB仿真

Simulation of the optical image recognition by using MATLAB

光学图像识别有两种主要的实现方式,其一是采用VanderLugt相关器,其二是采用联合变换相关器。这两种技术都是建立在4f光学成像系统基础之上的。MATLAB提供了丰富的图像处理函数,它们能实现4f光学成像系统的变换功能。利用这些函数可以模拟光学图像识别技术对图像的识别,能得到较好的仿真结果。

The technology of optical image recognition have two principal implementation method. One is Vander lugt correlator, the other is joint transform correlator. Both of the methods are based on the 4f optical imaging system. This article proposes a novel method to simulate the optical correlator in image recognition by using the image processing functions provided by MATLAB, which can realize the transformation function of the 4f optical imaging system. In the simulation experiments, the results which can be consistent with the real coherent optical pattern recognition experiments can be obtained. This method can assist the research in the pattern recognition field.
