【摘要】 本文中研究了正交傅里叶－梅林矩变换在光学模式识别中的应用，并用正交傅里叶－梅林矩变换表示了平移、比例、旋转、强度这四种畸变。通过适当的归化处理，正交傅里叶－梅林矩变换能解决所有这四种畸变不变识别。此外，研究了基于正交傅里叶－梅林矩变换的光学相关模式识别的实现问题更多还原

【Abstract】 We have studied the application of orthogonal Fourier Mellin Moments (OFMMs) in optical pattern recognition in the paper.The four distortions of shift,scale,rotation and intensity have been expressed by OFMMs.By the proper normalization,all the four distortions invariant pattern recognition can be solved by the orthogonal Fourier Melling Moments.In addtion,the implementation of the optical correlation pattern recognition based on orthogonal Fourier Mellin Moments is studied.更多还原
