摘要：
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. (C) 2002 society of Photo-Optical Instrumentation Engineers.
