document: Adaptive digital watermarking using fuzzy logic techniques Digital watermarking has been proposed for copyright protection in our digital society . We propose an adaptive digital watermarking scheme based on the human visual system model and a fuzzy logic technique . The fuzzy logic approach is employed to obtain the different strengths and lengths of a watermark by the local characteristics of the image in our proposed scheme . In our experiments , this scheme provides a more robust and imperceptible watermark
