说明:  实现图像处理中,实现对一幅灰度图像的快速傅立叶变换,并求其变换后的系数(幅度)分布,同时实现对一幅图像做离散余弦变换,选择适当的DCT系数阈值对其进行DCT反变换
(Realize image processing, to achieve the fast Fourier transformation of a grayscale image, and determine the distribution of its transform coefficients (amplitude), while achieving a discrete cosine transform of an image do, to select the appropriate threshold value of the DCT coefficients to the DCT inverse transform)
