基于OpenCV和FFTW实现的相位相关图像匹配程序，需要OpenCV和FFTW库文件的支持。本程序并没有用到OpenCV中的DFT，而是用了FFTW中的FFT，所以速度要快很多。-Based on OpenCV and the FFTW implementation phase correlation image matching procedures, require OpenCV and FFTW library files. This procedure does not use OpenCV in the DFT, but with the FFTW in the FFT, so much faster.
