将feature matching 转化为spatial sample,基于noise sample,进行聚类;非clusters的sample,视作outlier
略
通过实验(不同参数值;F-score为指标;多种数据集:30 randomly chosen image
pairs involving different types of transformations),得到全局最优参数
N:sample number
enhance the motion consistence among neighboring feature points
distance measurement function:Gaussian kernel distance //Euclidean distance(本文)
通过实验说明:predefined parameter 效果不好
衡量指标:recall、precision、F-score
此方法,对cluster border inliers而言,不稳定,容易造成误判
解决办法:density-based inlier(见下文5.3);
