| Abstract: | Analysis of the human visual system(HVS)characteristics, a new scheme which based on the human visual system characteristics, image brightness and texture features have been designed. The scheme makes use of HVS, embed the watermark into the brightest area and the intricate texture area. After testing, the scheme has a higher transparency and stronger robustness. |
