基于GVF和VFC主动轮廓模型代码，代码采用matlab编写，另外有C语言编程提供更快运行速度(VFC based GVF active contour model and code, code written using matlab, another C programming language to provide faster speed)

image processing and key generation etc

Wiener Scalart96维纳滤波算法，是1996年Wiener发明的算法。用于跟踪噪声信号，然后通过噪声信号的频谱图，将信号进行过滤(Wiener Scalart96 Wiener filtering algorithm, Wiener 1996, invented the algorithm. Used to track the noise signal, and then the noise signal spectrum, the signal filtering)

进行平面阵的声聚焦仿真，可改变阵元间距，聚焦点距离来讨论平面阵的聚焦效果(Planar Array acoustic simulation focus, may change the array element spacing, the focal point for discussion the focusing effect of the plane array)

this is DOA estimation algorithm

说明：  相关性的matlab程序，主要描述多个函数相关特性之间的关系的。(relevance of Matlab procedures, describing a number of functions related to the relationship between the characteristics of the.)

Hi This mfile is source code for image segementation using active contour models [Snake]. It found the objects in imaages.

视频监控，如果有东西经过监控区域就语音报警（有贼闯入）利用帧之间做差的方法(Video surveillance, if there are things after monitoring the regional voice alarm (the thief broke into) the use of the frame do the difference between method)

说明：  采用离散再合成的随机流动生成(DSRFG)方法合成了满足目标湍流度、积分尺度、脉动风速谱及空间相关性等参数的各向异性湍流;讨论了DSRFG方法在生成湍流风场上关键参数的合理取值;(Anisotropic turbulences satisfying the parameters of target turbulence, integral scale, pulsating wind speed spectrum and spatial correlation are synthesized by discrete resynthesis random flow generation (DSRFG) method. The key parameters of DSRFG method in generating turbulent wind field are discussed. Reasonable value;)

说明：  最短路径问题的重要算法实现。已知点的邻接矩阵，可计算出出发点至目标点的最短路径即最短路径长度(The important algorithm implementation of the shortest path problem. Given the adjacency matrix of points, the shortest path length from the starting point to the target point can be calculated)
