Das Schleifen von Schnittwerkzeugen,tion in the Contourlet domain. Consequently, the watermark is embedded into those stable features with QIM method. Experimental results show that the proposed scheme has some superiorities in terms of robustness and imperceptibility, which could against most common attacks such as JPEG compression, filtering, cropping, noise adding and so on.烧瓶 发表于 2025-3-27 05:08:11
