首先对指纹中的每个细节点定义具有很好区分度的子结构,根据这些子结构计算相似度并筛选出可能的参考点对。然后利用它们之间的边角关系等结构信息实施奖惩得分制度,根据事先设定的阈值,得分较高的参考点对被保留进行最终的全局匹配并计算匹配得分,两幅指纹的最终的匹配得分就是这些分数的最大值。实验结果表明,本文提出的匹配算法在性能下降可以忽略的情况下能够大幅度降低匹配时间。
传统目标跟踪检测方法对多目标情况处理已较为困难,对群体目标监测和跟踪更是难以解决的问题。因此考虑在拉格朗日混沌动力学基础上实现对视频群体流的分割以及相关检测。把群体运动系统作为混沌动力学系统处理,而群体目标则作为流动的粒子群处理,粒子的流动以流图(flow map,FM)进行跟踪。在此基础上可以获得有限时间李亚普诺夫指数(finite time Lyapunov exponent,FTLE)场,形
