| 摘 要： | 首先介绍TSUSAN（Smallest Univalue Segment Assimilating Nucleus）边缘检测算子的工作原理及在特征点提取中的应用，改进TSUSAN算子阈值的自动获取方法。最后将改进的SUSAN算子应用在图像配准中，通过计算候选匹配角点对，然后利用图像间的不变信息对候选匹配角点对进行筛选，最终得到正确的匹配角点对集。试验表明了该方法的有效性和可靠性。

| Abstract: | The SUSAN operator is introduced firstly,and then an improved method is presented about how to get the threshold value automatically.We use the improved method on the technique of image matching.Firstly ,comer points are extracted using SUSAN operator.Then matched comer pairs are selected through the invariability of images.Finally the right matched comer pairs are obtained.The experiments demonstrate the feasibility and reliability of this method. |
