[Algorithm] fft

Description: 由上述实验过程的图像变化可知，经过傅立叶变换和反变换及DCT离散余弦变换和反变换后，图像都发生了很大的变化，首先是经过2-D傅立叶变换后，图像数据频域出现高频数据集中，低频数据在四周的现象，然后再经过2-D傅立叶变换反变换后，图像再次恢复原始图。而2-D离散余弦变换对图像的影响也是如此。-From the above experiment, we can see the image change, after Fourier transform and inverse transform and DCT discrete cosine transform and inverse transform, the images have changed a lot, first of all, is a 2-D Fourier transform, the image data emergence of high-frequency frequency-domain data, low-frequency data in the four weeks of the phenomenon, and then after a 2-D Fourier transform inverse transform, the image again to restore the original map. And 2-D discrete cosine transform on the impact of images is also true.
