Description: 利用傅里叶变换，在频域上对两幅图像配准，是一种比较配准的新方法，但是对弹性配准的效果不是很好 需要进一步的研究。-Registers two images (2-D rigid translation) within a fraction of a pixel specified by the user. Instead of computing a zero-padded FFT (fast Fourier transform), this code uses selective upsampling by a matrix-multiply DFT (discrete FT) to dramatically reduce computation time and memory without sacrificing accuracy

Description: Images passed to your application are not always of the same size as your
templates. To compare them you might need to up scale or down scale them to
the template size. It is preferred that when comparing you check the size of the
template to be compared then adjust the size of the incoming image to be
compared. For simplicity you can do it for the following sample only.
Hints:
• Upsampling by interpolation/replacement
• Downsampling by interpolation/replacement
• Refer to sample code given in first tutorial for ways to create
images of similar width and height.-Images passed to your application are not always of the same size as your
