An extension of DHSPT to color half-tone images
Mitsuji Muneyasu, Masaaki Inoue, Y. Kitamura · 2005
The data hiding smart pair toggling (DHSPT) technique is one of watermarking techniques for grayscale halftone images. This paper proposes an extension of DHSPT to color images and its improvement technique of watermarked halftone image quality by considering luminance components. Simulation examples show the good image quality of the proposed technique.
