WebThe 'Fourier Transform ' is then the process of working out what 'waves' comprise an image, just as was done in the above example. 2 Dimensional Waves in Images ... ( … WebTools. In mathematics, the graph Fourier transform is a mathematical transform which eigendecomposes the Laplacian matrix of a graph into eigenvalues and eigenvectors. Analogously to the classical Fourier Transform, the eigenvalues represent frequencies and eigenvectors form what is known as a graph Fourier basis .
