LEVEL SET算法，写得很清楚，好用。 (Level Set Evolution Without Re-initialization: A New Variational Formulation)

用于模型参数的在线辨识，能有效地实现参数的整定等(For online identification of the model parameters, tuning parameters)

基于卡尔曼滤波的机器人定位及地图创建（salm），对1D、2D、3D等情况分别进行仿真(Kalman filter-based robot localization and map building (salm), on the 1D, 2D, 3D, etc. were simulated)

说明：  约束优化进化算法，采用多目标优化算法的思想求解约束优化问题(constrained optimization evolutionary algorithms)

对于显著性区域进行标注，同时输出STD，最大值，最小值(Significant area for labeling, while the output STD, maximum, minimum)

说明：  关羽调频广播的很好的几篇文章，值得一看。(Guan Yu, a good FM radio articles, worth a visit.)

利用Matlab软件编写的轨道不平顺数据分析程序能够对轨检车测得的不平顺数据进行处理,得到功率谱密度分布函数.轨道不平顺分析程序包括轨道不平顺数据预处理、轨道不平顺谱分布函数计算以及根据实测的车体振动加速度,对轨道不平顺与车体振动加速度进行相干分析、提出对行车运行有不利影响的不平顺波长范围等.研究结果表明:车辆的动力特性与轨道不平顺有密切关系.高低不平顺对车体垂向振动影响显著,轨向不平顺对车体水平振动影响显著,水平不平顺对列车垂向、横向振动均有显著影响.(Matlab software written track irregularity data analysis program able to track inspection car irregularity measured data are processed to obtain the power spectral density function. Track Irregularities track irregularity analysis procedures including data preprocessing, track irregularity spectrum distribution function calculations, and based on the measured vibration acceleration of the vehicle, with the body of track irregularity acceleration coherent analysis, have an adverse impact on traffic running irregularity wavelength range, etc. the results show that: the dynamic characteristics of the vehicle and the track irregularity closely related. rough along the vertical vibration of the vehicle significantly, rail irregularity vibration to levels significantly affect the body, the level of irregularity to train the vertical and horizontal vibration significantly affected.)
