"WebThe concept of using the Fourier domain for CNN operations has been previously proposed [7,14,15]. In both [7] and [14] the speed-up of convolution in the Fourier domain was demonstrated. Down-sampling within the Fourier domain was used in [15] where the ability to retain more spatial information and obtain faster convergence was demonstrated. " - Fourier s2cnn
