Abstract

We present a reversed unsharp masking technique for sharpening images by producing hue halos around edges. This technique is used to binarize images. In the reversed unsharp masking, a detailed component in the usual unsharp masking is reversed and added to a base component. Images sharpened with this masking are then thresholded to generate non-photorealistic binary images.
