Digital watermarking is the process of computer-aided information hiding in a carrier signal with robust and concealment characteristics. A halftone image quality assessment framework based on digital watermark is proposed. First, we segmented image dark tong area and edge through C-V model and transformed segmentation image into binary image to obtain the area in which watermark is to be embedded. Then, the watermark was embedded and the image quality assessment was completed by extracted watermark. The experimental results show that the presented quality evaluation scheme of halftone image can detect printed image quality efficiently with the characteristics of novel and rapid.
