Abstract

Sharpening images using conventional highpass linear filters can result in two serious problems: An increase in the level of image noise and the addition of error which results from clipping pixel values to within the range [0,1]. We have found that these two problems are closely related. By modifying the neighborhood of each clipped pixel, we reduce its perceptibility and reduce image noise.
