小波变换人脸特征提取

无人机如何在复杂的战区自主飞行是时下的一个热点。这里采用了蚁群算法做出了探讨。并用matlab实现。假定无人机的活动范围为20km×20km的区域，无人机起点的平面坐标为[1,2][单位：km], 攻击目标的平面坐标为[19,18][单位：km]，同时不考虑无人机起飞降落时的限制。数字地图和敌方威胁情况[主要考虑雷达威胁]已在附件中给出。数字地图可以做适当的简化，比如可以把地形近似分为三种：高地，低地以及过渡地带。 忽略地形和无人机操作性能等因素的影响，综合考虑敌方威胁，无人机航程等，基于二维平面建立单机单目标的航迹规划模型。( ant,plane)

 检查数据：如果某一组转速N下数据点少于5个点，给出提示：“数据点少不能绘制曲线”。  插值：每一条转速N线上的测量点个数可能不一样，按照测量点数最多的个数，将测量点少的数据插值成测量数据点最多一样的个数 ( check data: If a group speed N under the data point is less than 5 points, hints: " The few data points can not draw a curve. The  interpolation: each a speed N line, the number of measurement points may be different, in accordance with the maximum number of measurement points, the measurement point less data is interpolated to the measurement data points up the same number of)

追逐问题是现实生活中的常见问题,本文就三人绕正三角形的追逐问题建立起了两个数学模型:一个充分应用运动的周期性首先给出了三人共边的充要条件,然后直接给出在一个周期内三人共边的次数及起止时刻,另一个则利用初等数论的方法给出了三人共边的另一个充要条件 利用matlab长于计算和强大的绘图功能,本文分别给出了求解两个模型的matlab程序,通过动画仿真演示三人绕正三角形的追逐模型,并给出三者共边的时间起止点和共边的次数。 更多还原 (The problem is that in real life the pursuit of the common problems, the paper chase on three questions about the triangle established two mathematical models: a full application of the cyclical movement Firstly, the necessary and sufficient conditions of the three sides, and then directly within a given period of three sides of the starting and ending times and moments, and the other using elementary number theory approach gives another three necessary and sufficient conditions of the edge using matlab longer computing and powerful graphics capabilities, this paper two models are given for solving matlab program, triangle chase through animated simulation model demonstrates trio around and gives the time of the beginning and ending points of the three sides and the number of edges.
