Paper Abstract

The linear unsharp masking technique used in image contrast enhancement is modified in this article by introducing a control term expressed as a rational function of the local input data. In this way noise amplification is avoided and, at the same time, overshoot effects on sharp edges are limited. Experimental results support the validity of the method, even as a preprocessor for interpolation systems.
