Hashing by Proximity to Process Duplicates in Spatial Databases
In a spatial database, an object may extend arbitrarily in space. As a result, many spatial data structures e.g., the quadtree, the cell tree, the R+-tree represent an object by p...

Multidimensional Dynamic Quantile Hashing is Very Efficient for Non-Uniform Record Distributions
: Previous multidimensional dynamic hashing schemes exhibit two obvious shortcomings. First, even for uniform record distribution, the retrieval performance of these schemes suffer...
