| 摘 要： | 为了实现图像的自动匹配,提出了一种新的SIFT匹配策略.首先,给定一个基本的欧式距离最小值与次小值的比率值,对SIFT特征对进行判断,得到粗匹配集合.然后,统计粗匹配对的主方向角度差直方图和最小欧式距离直方图,以主方向角度差落入直方图峰值所在邻域和最小欧式距离小于直方图主峰所对应的距离值作为匹配条件进行精匹配.最后,统...

| Abstract: | For the purpose of actualizing automatic image matching,a new Scale Invariant Feature Transform(SIFT) matching strategy is presented.Firstly,compared with the given basal ratio of Euclidean distance from the closest neighbor to the distance of the second closest of features,the coarse matching collection of SIFT is obtained.Then,obtain the histogram of coarse matching corresponding points' main direction angle differences and the histogram of minimum Euclidean distances.The precise matching is taken under t... |
