Abstract

Inverse halftoning is the problem of recovering a continuous- tone image from a given halftoned image. In this paper, a new inverse halftoning method which uses a set theoretic formulation is introduced. The new method exploits the prior information at hand, and uses space-domain projections, frequency-domain projections, and space-scale domain projections to obtain a feasible reconstruction of the continuous-tone image. The proposed method is also extended for the inverse halftoning of color error-diffused images.
