The effect of the observation Fourier sign correction for image sharpening
An image edge sharpening technique with Fourier phase correction is presented. The technique here includes a traditional one (Laplacian operator) and phase-only synthesis with the corrected Fourier phase. A human visual property is also introduced as a weighted function in order to maintain the natural smoothness in the gray level of the image. Simulation examples show that the proposed technique is much superior to the traditional one.
