分层聚类与Flann opencv [英] Hierarchical Clustering with Flann opencv

问题描述

我有一个问题，我需要聚集一组点在未知数量的集群。我使用opencv，但没有关于 cv :: flann :: hierarchicalClustering 的文档。有人使用这个功能可以帮助我吗？另一个问题是关于返回值应该是集群的数量，但我怎么能理解哪些集群？
我创建了一个 cv :: Mat points ，尺寸为 nx 2 其中n是点数。

I have a problem, I need to clusterize a set of points in an unknown number of clusters. I use opencv but there is not documentation about cv::flann::hierarchicalClustering. Someone that use this function could help me? Another question is about the return value that should be the number of clusters, but how could I understand which are the cluster? I created a cv::Mat points with dimensions n x 2 where n is the number of points.

提前感谢。

推荐答案

功能，请此处。返回值的确是发现的簇数。 I GUESS，然后找到哪个簇属于const Mat& C的每个特征向量。特征参数使用Mat&

There is a documentation for this function, here. The return value is indeed the number of clusters found. I GUESS that you then find to which cluster belong each feature vector in the const Mat& features parameter using Mat& centers.
