A novel attribute-based framework is proposed to tackle the problem of halftone watermarking in combination of the spatial/transformation domain.The challenge is that the host image is continuous,while the watermarked halftone is bi-level.To search for a solution,an attribute image is defined as a good connection between the original grayscale image and its halftone image.When the attribute image is used as a watermark carrier,it helps to find the watermarked halftone efficiently by solving a constrained mo...

Received 2014-06-12Digital halftoning[1]is the technique of render-ing continuous tone images on binary display de-vices and printers which can reproduce image onlyin two levels,black and white.A halftone image isperceived as continuous tone image when vi
