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 ...

Abstract: Image enhancement in the transform domain is an indispensable technique in the image processing area. In this paper, a novel method of image enhancement with respect to the fractional ...
