本文通過對圖像特點的分析，并根據人類視覺對圖像邊緣、紋理等區域感知的模糊
性，利用模糊控制方法對非線性的、無法獲得精確數學模型的復雜系統的良好控制性能，提 出了一種對水印強度進行智能控制的算法，使水印強度能夠完全自適應于原始圖像，較好的 平衡了不可見性和魯棒性之間的矛盾。實驗結果表明，按照該算法對水印進行動態嵌入，使 水印具有良好的不可感知性。該算法易于實現，并有利于數字水印的實時性應用，有實際應 用價值。

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.
