在RGB、HSV、YCBCR空间提取得到了高质量的印章，算法鲁棒性很强。(the seal is well recognized in the space of RGB、HSV and YCBCR,and the method is robust.)

相空间重构相关代码,使用重构相空间捕捉非线性特征。(phase space reconstruction.This toolbox contains Matlab functions to capture the nonlinearities of the speech production system using reconstructed phase space (RPS) techniques.)

用牛顿-拉夫逊算法求解线路中的潮流运算，能够求解各节点电压降，线路网络损耗(Newton- Raphson algorithm for computing the trend line, each node can solve the voltage drop line network losses)

说明：  该函数用于演示BAS应用于路径规划, 当天牛跑到界外时，相当于跑一个非常大的反馈(This function is used to demonstrate the application of BAS to path planning)

本程序实现1D声波正演，擦用Clyton单程波吸收边界条件。(This program implements 1D acoustic wave equation, rub with Clayton one-way wave absorbing boundary condition)

帮朋友写的主成分分析，有图形显示，注意请自行判断数据是否需要转置。(Help a friend wrote principal component analysis, a graphic display, attention please judge for themselves whether the data needs to transpose.)

XCODE超级玛丽，部分oc，部分c++(SuperMario，made by xcode)

This matlab file is used to rounoff the decimals values into nearest whole number

说明：  对信号进行EMD分解并绘制希尔伯特时频谱的程序，自己做毕业设计编写的( EMD decomposition of signals and time-frequency spectrum of the Hilbert mapping procedures, the design of their own graduates prepared )
