A new scale distortion invariant pattern recognition method by fractional correlation
-
摘要: 推导了“菲涅耳衍射透镜相位变换”及“透镜相位变换菲涅耳衍射”两种光学单元所遵从的约束关系,并基于此提出了一种分数相关尺度畸变不变识别方法。数值模拟试验结果表明,对于一个尺度畸变的待识别输入,当传统相关已无法正确识别时,该方法仍能够较好地识别畸变目标。

Abstract: The constraints between two units are analyzed.Based on the results and fractional correlation theory,a new scale distortion invariant pattern recongnition method is proposed.Simulation results show that when a scale distortion inputimage can't berightly recognized by the conventional correlation,it can be recognized well with the method. -
