An image is represented by the Fourier transform as a sum of complex exponentials of varying magnitudes, frequencies, and phases. Several image processing applications use the Fourier transform for ...

Instead of representing the image as a grid of pixel values, the Fourier transform represents the image as a sum of sinusoidal functions of different frequencies and amplitudes. These sinusoidal ...

A novel image enhancement method is presented in this paper. We apply the idea of Laplacian Pyramid and generalize it into the fractional Fourier domain to extract some image information. Firstly, we ...
