Abstract: Based on the analysis of the characteristics of the image, and in accordance with the
human visual image on the edge of the region, such as texture perception of ambiguity, the use of fuzzy control methods for non-linear, lack of access to accurate mathematical models of complex systems to control a good performance, put forward a Kind of watermark on the strength of intelligent control algorithm, so that the watermark is fully adaptive to the strength of the original image, a better balance between the invisible robustness and resolve their conflicts. The results show that, in accordance with the method of dynamically embedded watermark, so that the watermark can not have a good perception of. The algorithm is easy to implement, and is conducive to the real-time digital watermarking applications, there is a practical application.
