Abstract

Abstract

En 中文
A class of inverse halftoning algorithms that recovers gray-scale (continuous-tone) images from halftone images is proposed. The basic structure is an optimized linear filter, Then, a properly designed adaptive postprocessor is employed to enhance the recovered image quality. Finally, a multistage space-varying algorithm is developed that uses the basic linear filter structure as before but with spatially adaptive parameters.
