Spectral Reconstruction Function: Spectral Complexity and Its Connection to Barron Norms

We introduce the Spectral Reconstruction Function (SRF), a cumulative descriptor ofthe spectral content of a digital image. The construction is based on the discrete Fourierdecomposition of an image and on the radial frequency associated with each Fourier mode. TheSRF measures th...
