CS425 Lab: Frequency Domain Processing

MATLAB has three functions to compute the DFT: 1. fft -for one dimension (useful for audio). 2. fft2 -for two dimensions (useful for images).

Fourier approximation. Applications to Image Processing

The DFT and its inverse are obtained in practice using a fast Fourier Transform. In Matlab this is done using the command fft2: F=fft2(f).
