abstract = "This paper presents a halftoning-based watermarking method. This
method enables the embedding of a color image into a binary
black-and-white halftone, while maintaining the image quality. The
proposed technique is capable of embedding watermarks of three
color channels into a binary halftone. To achieve high quality
halftones, the method maps colors to halftone channels with
homogeneous dot patterns which in turn use different binary
texture orientations to carry the watermark. They are obtained by
solving a minimization problem in which the objective function is
the binary distance between the original binary halftone and the
available patterns. To restore the color information, we scan the
printed halftone image and compute the inverse information
(considering the dot pattern). Using the mapped information, we
restore the original color channels from the halftone images using
a high-quality inverse halftoning algorithm. Experimental results
show that the method produces restorations with a superior quality
than other methods found in the literature and increases the
embedding capacity.",
