WebJan 1, 2024 · Hilbert R-tree is an index structure for multidimensional objects which commonly appear in Multimedia databases, Geographical Information Systems (GIS), and medical databases. For example, in multimedia databases, objects like images, voice, video, etc. need to be stored and retrieved. WebThe R-tree is an indexing scheme that has been originally proposed towards organizing spatial objects such as points, rectangles and polygons. It is a hierarchical data structure suitable to index objects in secondary storage (disk) as well as in main memory.

WebJan 1, 2024 · The Hilbert R-tree (Kamel and Faloutsos 1994) is a hybrid structure. It is a B + -tree with geometrical objects being characterized by the Hilbert value of their centroid. The structure is based on the Hilbert space-filling curve which has been shown to preserve the proximity of spatial objects very well. more importantly, we introduce a dynamic variation, the Hilbert R- tree: : Given the ordering, every node has a well- defined set of sibling nodes; thus, we can deploy the deferred splitting algorithms of the B* -trees. By adjusting the split policy, the Hilbert R-tree can achieve as high ...

WebAug 31, 2008 · By adjusting the split policy, the Hilbert R-tree can achieve as high utilization as desired. To the contrary, the R*-tree has no control over the space utilization, typically achieving up to 70%.

WebIt uses the Hilbert Curve to order the keys in an RTree, which places close points relatively close in the tree. This makes it efficient to find other near points or intersecting points because much of the time all the geometric features inside a bounding box are all on the same branch of the tree.
