Description: In the Fourier transform domain, the transform coefficients reflect some characteristics of the image. DC low frequency spectrum corresponding to the image of the smooth area, and superimposed noise outside the frequency corresponding to the higher part of the spectrum and so on. Construct a low-pass filter, the low frequency components and effectively prevent the smooth passage of high frequency components, you can filter out high frequency noise in the frequency domain, and then the inverse transform to get a smooth image.
