Image Sharpening & De-Noising Using An Adaptive Bilateral Filter

Abstract

The scope of this project is to deal with images that are appropriate for digital photography. The problem we are interested in is twofold. First to develop a sharpening method that increases the slope of edges without producing overshoot and undershoot, which renders clean, crisp, and artefact-free edges, thereby improving the overall appearance of the image. The second aspect of the problem is to address noise removal. In most applications, the degraded image contains both noise and blur. A sharpening algorithm that works well only for noise-free images will not be applicable in these situations. Hence a unified solution to both sharpness enhancement and noise removal is proposed.
