数学形态变换的光学实时实现及其应用

OPTICAL PROCESSOR FOR REAL-TIME MORPHOLOGICAL TRANSFORMS AND ITS APPLICATIONS

基于多焦点透镜的成像关系和光学实时器件,提出一种紧凑的非相干光学处理系统以实现实时数学形态变换.用光学方法实现了形态学中膨胀、腐蚀、开和闭等基本运算,并用这套光学系统对具有胡椒盐(Pepper and salt)噪声的输入图像进行处理,得到无噪声干扰的图像输出,还给出了指纹经过系统骨架化的实验结果.

A compact incoherent optical processor based on multifocus lenses and real-time devices is proposed to implement real-time optical morphological transforms. Dilation, erosion, opening and closing, which are the basic operations in morphology, are performed optically. Inputs with pepper and salt noise are processed through this processor and noiseless outputs are obtained. The experimental results of the fingerprint skeletonization are also given.
