| 摘 要： | 首先对基于频域的抗旋转匹配算法和相关函数傅里叶变换匹配算法做了研究和分析,然后在相关函数傅里叶变换匹配算法的基础上,研究讨论了基于快速傅里叶变换和积分图的匹配定位算法,从而证明了基于频域相关技术做图像匹配具有相关峰尖锐突出、精度高、抗噪、对局部灰度变化不敏感等优点。

| Abstract: | This paper firstly studies and analyses the anti-rotation based on frequency domain correlation function matching Fourier transform algorithm and matching algorithm, then studies and discusses the fast Fourier transform and the integral positioning graph matching algorithm which based on the correlation function Fourier transform matching algo- rithm. Finally it proves that image matching technique based on the frequency domain is highlighted with a sharp correlation peak, high precision anti noise, not sensitive to the local gray and so on. |
