非线性图像水印理论与技术综述

Theory and technology survey of nonlinear image watermarking

针对图像水印应满足隐蔽性、鲁棒性和安全性等基本特性的要求,运用非线性科学中的混沌、分形等理论,围绕非线性图像水印概念,全面概括总结了混沌、分形、神经网络和遗传算法等非线性理论与技术在非线性图像水印中的研究现状。

According to the basic requirements of imperceptibility, robustness and security in image watermarking, this paper introduced nonlinear science such as chaos and fractal. Using the new conception of nonlinear image watermarking, an actual research survey is given out that the theories and technologies of chaos, fractal, neural networks and genetic algorithm are applied into the area of nonlinear image watermarking.
