摘要 从特征点的检测入手,采用了Harris算子来检测图中的特征点,并且分析各种点匹配的策略(如ZNCC,不变向量测度)从中找出不足。然后把证据理论应用到特征点的匹配当中,构造组合的证据理论框架,并且提出了匹配策略的规则。最后,把双向测试的方法也应用到特征点匹配当中。综合多种点匹配策略,从而得到了一种有效的特征点匹配算法。 An algorithm for how to detect interest point is presented firstly. And then, some kinds of matching algorithms are analyzed,such as ZNCC, Moment invariants. Finally, we introduce Dempster- Shafer's evidential reasoning into interest point matching, fusing lots of matching algorithms to get a robust interest point matching algorithm.
