Abstract
The development of image sharpening algorithms is currently one of the most important problems in image processing. This paper presents a parallel implementation of a pixel grid warping algorithm for image sharpening. To sharpen image edges, the proposed algorithm moves pixels in the edge neighborhood towards edge centers rather than changing pixel values directly. This approach does not increase noise and does not cause ringing artifacts.
