中文说明:
二维傅立叶变换的Matlab实现,是利用图像处理软件对给出的图像进行傅立叶变换处理。在Matlab中,函数fft2表示二维傅立叶变换,函数ifft2则表示二维傅立叶反变换。
English Description:
The realization of two-dimensional Fourier transform with MATLAB is to process the given image by using image processing software. In MATLAB, the function fft2 represents two-dimensional Fourier transform, and the function ifft2 represents two-dimensional inverse Fourier transform.
