Implicit kd-tree — An implicit k d tree is a k d tree defined implicitly above a rectilinear grid. Its splitting planes positions and orientations are not given explicitly but implicitly by some recursive splitting function defined on the hyperrectangles belonging… … Wikipedia
Hilbert R-tree — Hilbert R tree, an R tree variant, is an index for multidimensional objects like lines, regions, 3 D objects, or high dimensional feature based parametric objects. It can be thought of as an extension to B+ tree for multidimensional objects.The… … Wikipedia
Kd-tree — In computer science, a k d tree (short for k dimensional tree ) is a space partitioning data structure for organizing points in a k dimensional space. k d trees are a useful data structure for several applications, such as searches involving a… … Wikipedia
B-tree — In computer science, a B tree is a tree data structure that keeps data sorted and allows searches, insertions, and deletions in logarithmic amortized time. It is most commonly used in databases and filesystems. In B trees, internal (non leaf)… … Wikipedia
Kd-trie — A k d trie is a spatial data structure for indexing points in k dimensional space. It is a variation on the k d tree that only stores points in the leaf nodes, sometimes in small collections called bins or buckets. Internal nodes only store the… … Wikipedia
