二维傅里叶变换,对图像进行二维傅里叶变换处理(Two-Dimensional Fast Fourier Transform
The purpose of this project is to develop a 2-D FFT program "package" that will be used
in several other projects that follow. Your implementation must have the capabilities to:
(a) Multiply the input image by (-1)x+y to center the transform for filtering.
(b) Multiply the resulting (complex) array by a real function (in the sense that the
the real coefficients multiply both the real and imaginary parts of the transforms).
Recall that multiplication of two images is done on pairs of corresponding elements.
(c) Compute the inverse Fourier transform.
(d) Multiply the result by (-1)x+y and take the real part.
(e) Compute the spectrum.)

HHT是历史上首次对Fourier变换的基本信号和频率定义作的创造性的改进。他们不再认为组成信号的基本信号是正弦信号,而是一种称为固有模态函数的信号(HHT is the first time in the history of the Fourier transform basic definition signals and frequencies for creative change Progressive. They will no longer signal that the basic component signal is sinusoidal signal, but as an intrinsic mode function signals)
