    • Novel methods in image halftoning 

      Bozkurt, Gözde (Bilkent University, 1998)
      Halftoning refers to the problem of rendering continuous-tone (contone) images on display and printing devices which are capable of reproducing only a limited number of colors. A new adaptive halftoning method using the ...
    • QR-RLS algorithm for error diffusion of color images 

      Unal, G. B.; Yardimci, Y.; Arıkan, Orhan; Çetin, A. Enis (SPIE, 2000)
      Printing color images on color printers and displaying them on computer monitors requires a significant reduction of physically distinct colors, which causes degradation in image quality. An efficient method to improve the ...
    • Restoration of error-diffused images using projection onto convex sets 

      Unal G.B.; Çetin, A.E. (2001)
      In this paper, a novel inverse halftoning method is proposed to restore a continuous tone image from a given half-tone image. A set theoretic formulation is used where three sets are defined using the prior information ...
