Searching in KD-tree slow

I\'m implementing a KD-tree to cluster points a map into groups. I\'ve been using Wikipedia\'s KD-tree article as a reference. The search returns the correct nearest neighbor point, but it is slower t[详细]

KD tree, slow tree construction

I am trying to build KD Tree (static case). We assume points are sorted on both x and y coordinates. For even depth of recursion the set is split into two subsets with a vertical line going through m[详细]

How to use KDTree to make top-k query and range query on arbitrary dimensions

I have used KD-tree(libkdtree++) to store开发者_开发技巧 a multi-dimensional data set, and the requirements here is this data set can support top-k/range queries on different dimensions. For example,[详细]

Alternative to distance metric in nearest neighbor algorithm?

I came across an implementation of the nearest neighbor algorithm for finding matches between certain keypoints in two similar images. The keypoints were generated by the SIFT algorithm. The points ar[详细]
