第五次作业
说明: 1.学习使用fft2,ifft2,fftshift,ifftshift函数。用fft2函数对”lena.bmp”做二维傅立叶变换,并显示其频谱,用fftshift函数将频谱坐标原点移动到图像中心。用ifft2函数做傅立叶反变换。(提示:显示频谱时,可以先对频谱取对数,这样可以压缩动态范围很大的频谱,获得更好的显示效果)(1. Learn to use fft2, ifft2, fftshift, ifftshift functions. With the FFT 2 function, the lena.bmp'The two-dimensional Fourier transform is performed and the spectrum is displayed. The origin of the spectrum coordinate is moved to the center of the image by using the FFT shift function. The inverse Fourier transform is done with ifft2 function. (Note: when displaying the spectrum, the logarithm of the spectrum can be taken first, so that the spectrum with a large dynamic range can be compressed to obtain better display effect.))
