Description: Image transform,As can be seen from the spectrum diagram of Fourier transform, the edge is smoother and the serrated is significantly reduced after improving the resolution. But the image of the Fourier transform did not change significantly.
3. The DC coefficient moves.
When the coefficients are moved, the spectral components are concentrated in the middle of the spectrum.
4) filter frequency response.
