应用傅里叶全息滤波器的光电图像形态学处理系统

AN OPTOELECTRONIC MORPHOLOGICAL SYSTEM USING FOURIER HOLOGRAPHIC FILTER

介绍一种使用傅里叶全息滤波器的光电图像形态学处理系统，其中关于图像结构元的扩张、侵蚀及开和闭等基本运算均基于傅里叶全息光学方法产生的图像与结构元的卷积结果，其迭代过程使用了计算机控制的电寻址空间光调制器．该系统具有结构简单、能反复迭代、易于根据图像设计。

An optoelectronic morphological system using Fourier holographic filter is introduced,in which all the basic operations of dilation,erosion,opening,and closing of an image about its construction element are executed based on the convolution of the image with the construciton element by Fourier holography.A computer controlled electronically addressed SLM is employed in the iteration process.The system is simple in construction,easy for multiple iteration,design and exchange of the construction element,and using computer generated hologram,as well as printing the output by computer directly.
