This program contains animations/demos for the following:
1. 1D Fourier transform & its inverse (on discrete random samples): reconstruct the original signal by adding the 1D FT sin's/cos's components together
2. 2D Fourier transform & its inverse (on any image): reconstruct the input image by adding the 2D FT sin's/cos's components together
3. Ringing effect of ideal filter
4. Gaussian filter: spatial-based vs. Frequency-based speedup
