Description: vb版本的fft变换，能够正反变换。正变换：
把时域信号转换成频域信号，反变换：能够把频域信号转换成时域信号。fft可广泛应用于工程领域，例如：信号的频域分析。震动，噪声的分析等等。-vb version of the fft transform, to transform pros. Transformation : put time domain signal into frequency domain signal, anti-transformation : can frequency-domain signal into time domain signal. Fft can be widely used in engineering fields, such as : the frequency-domain analysis. Vibration, noise analysis, and so on.

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.
