matlab 数字图像信号的频域分析及仿真
将二维数字图像进行傅立叶频域分析,并且做了图像幅度谱重建和相位谱重建,通过这个例子大家可以明白相位比振幅更重要。(matlab digital image signals in frequency domain analysis and simulation of two-dimensional digital image Fourier frequency domain analysis, and has done a reconstruction of the image amplitude spectrum and phase spectrum reconstruction, by this example we can understand the phase is more important than the amplitude.)
