代码说明:

数字多媒体内容的保护已成为越来越多内容所有者和服务提供商的重要问题。水印标识作为主要手段,实现版权保护。这种水印的算法基于离散小波变换 (DWT)。水印组件被添加到一个高通过考虑人类视觉系统 (HVS) 的低频子带特征。在此方案中各 HVS 特性用于开发鲁棒水印算法具有更好的鲁棒性之间的折衷和不可感知性。基于 HVS 特性的可视化掩码用于计算每个小波系数的主机的权重系数图像。拟议的计划进行了测试,大多是已知威胁和它被证明给鲁棒性好。也它仍然给出了一支高素质水印的图像。MATLAB 程序用于执行水印的任务。

    An implementation of Unscented Kalman Filter for nonlinear state estimation. (Nonlinear state estimation is a challenge problem. The well-known Kalman Filter is only suitable for linear systems. The Extended Kalman Filter (EKF) has become a standarded formulation for nonlinear state estimation. However, it may cause significant error for highly nonlinear systems because of the propagation of uncertainty through the nonlinear system. The Unscented Kalman Filter (UKF) is a novel development in the field. The idea is to produce several sampling points (Sigma points) around the current state estimate based on its covariance. Then, propagating these points through the nonlinear map to get more accurate estimation of the mean and covariance of the mapping results. In this way, it avoids the need to calculate the Jacobian, hence incurs only the similar computation load as the EKF. For tutorial purpose, this code implements a simplified version of UKF formulation, where we assume both the process and measurement noises are additive to avoid augment of state and a)

  • TSP(TravelingSalesmanProblem)
    Traveling Salesman Problem (TSP) has been an interesting problem for a long time in classical optimization techniques which are based on linear and nonlinear programming. TSP can be described as follows: Given a number of cities to visit and their distances from all other cities know, an optimal travel route has to be found so that each city is visited one and only once with the least possible distance traveled. This is a simple problem with handful of cities but becomes complicated as the number increases.
