Description: 使用非线性动力学中的一维和二维耦合格子模型研究两个声光双稳系统的时空混沌同步.将驱动系统的输出以适当的比例耦合到响应系统并进行均衡 , 能实现两系统的时空混沌同步.利用计算最大条件Lyapunov指数 , 给出达到同步所需的最小耦合强度与系统参数的关系. 数值实验表明 ,在小噪声影响时仍然可以实现两系统的同步 , 此法具有一定的抗干扰能力.-The use of nonlinear dynamics of one-dimensional and two-dimensional lattice model of coupled two acousto-optic bistable system of space-time chaos synchronization. Will drive the output coupling ratio appropriate to the response system and a balanced, able to realize the two systems spatiotemporal chaos synchronization. the use of calculating the maximum Lyapunov index, given the minimum required to achieve synchronous coupling strength and system parameters. Numerical experiments show that the effect of small noise can still realize the synchronization of two systems, this method has certain anti- interference.

Description: Firstly, research on robust image watermarking. A digital watermarking scheme based on wavelet transform was proposed. It realizes the watermarking extract without the original image using 64×64×8 bit gray image as the watermark signal. In order to enhancing the security of the watermark, we employ an encryption technology based on chaos and bit plan. Simulation results show that our scheme have good invisibility and can survive low-quality JPEG compression, median filtering and so on. In addition, the analysis of the extracted watermark can help us to detect and localize tampers.-Firstly, research on robust image watermarking.
