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: This a fast floating point to string conversion function. Avoids the use of unsafe sprintf function. Works with float and double types. Correctly manages +inf, -inf, nnan (not a number).-This is a fast floating point to string conversion function. Avoids the use of unsafe sprintf function. Works with float and double types.

Description: FT是一种FT的高效算法，称为快速傅立叶变换（fast Fourier transform），它根据离散傅氏变换的奇、偶、虚、实等特性，对离散傅立叶变换的算法进行改进获得的。(FT is an efficient algorithm for DEFT, called fast U Lie transform (fast Fourier transform). It is obtained by improving the algorithm of discrete U Lie transform according to the odd, even, virtual and real properties of the discrete Fourier transform. fast Fourier transform algorithm can be divided into time extraction algorithm and frequency extraction algorithm.First,the basic principle of FT is briefly introduced.)
