摘要
本文通过对图像特点的分析,并根据人类视觉对图像边缘、纹理等区域感知的模糊性,利用模糊控制方法对非线性的、无法获得精确数学模型的复杂系统的良好控制性能,提出了一种对水印强度进行智能控制的算法,使水印强度能够完全自适应于原始图像,较好的平衡了不可见性和鲁棒性之间的矛盾。实验结果表明,按照该算法对水印进行动态嵌入,使水印具有良好的不可感知性。该算法易于实现,并有利于数字水印的实时性应用,有实际应用价值。
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.
