Description:
该实验的目的是开发一个 2-D FFT程序包。要求程序能完成下面的功能:
(a) 用因子 (-1)x+y
乘以输入图像，以实现滤波的中心化变换；
(b) 用一个实矩阵乘以一个复数矩阵，即用实矩阵中的元素同时乘以复数矩阵对应位置上的复数的实部与虚部。
可以通过调用两个图像的乘法程序来实现对应元素的相乘；
(c) 计算反付立叶变换；
(d) 结果乘以 (-1)x+y
，并取其实部；
(e) 计算频谱。 -The purpose of this experiment is to develop a 2-D FFT package. Program to complete the following features: (a) The factor (-1) x+y multiplied by the input image to achieve the center of the transform of the filter (b) a real matrix is multiplied by a complex matrix, using the real matrix elements at the same time multiplied by the complex matrix corresponding to the position of the real part and imaginary part. By two images is called the multiplication process of multiplying the corresponding element (c) The calculation of the anti-Fourier transform (d) multiplying the result by (-1) x+y, and take the real part (e) The calculation of the spectrum.
