Abstract

This paper proposed an algorithm of extracting feature points based on multiple criterions, which aimed to extract boundary feature points and sharp feature points efficiently. Firstly, the algorithm built the point cloud topological structure based on a modified k-d tree approach to search for the K-nearest neighborhood of the sample point. Then, according to each K-nearest neighborhood points, it calculated three feature parameters based on vector angle criteria, kernel density criteria and field power criteria. Finally, according to the three parameters, it obtained feature discriminant parameters and the global fixed threshold. It recognized a point as the feature point when its value of discriminant parameter was bigger than the threshold. The experimental results show that the proposed algorithm can extract boundary points and sharp feature points effectively.
