Abstract

In this paper, a novel digital watermarking scheme for halftone image is proposed. Halftone images are obtained by used of the weighted least-squares model-based(WLSMB) and cluster method. We applied to embed digital watermark to protect the suffering during transmission compression attacks and geometric attacks robustness. Experimental results show that the presented halftone image watermarking is invisible and robust against various signal processions such as JBIG compression, noise adding, cropping, daubing and print-scan.
