fftnew
- 用C++编写的比较dft算法，有待优化成为fft算法，请提意见-C dft index prepared by the comparison algorithm, as fft pending optimization algorithm, please comment
ImageTest4
- 注意事项： 1>在进行DFT时，强烈建议选用64*64的图像，选用256*256的图像，**时间太长，中间可能导致死机**。 2>程序中在显示频谱图像时有两种方式，即移至中心和未移至中心，可以通过将/** pow(-1, x+y)*/的注释去掉来进行转换。 由于本程序使用了VFW组件，所以在Project－－Setting中－－Object/libray modules中添加vfw32.lib。 -Note : 1
