FLANN - Fast Library for Approximate Nearest Neighbors

Compare

  Analyzed about 7 hours ago

FLANN is a library for performing fast approximate nearest neighbor searches in high dimensional spaces. It contains a collection of algorithms we found to work best for nearest neighbor search and a system for automatically choosing the best algorithm and optimum parameters depending on the ... [More] dataset. FLANN is written in C++ and contains bindings for the following languages: C, MATLAB and Python. [Less]

PH-Tree

Compare

  Analyzed 1 day ago

The PH-Tree is a multi-dimensional spatial index structure. It is a 'trie' version of a quadtree. Properties: no rebalancing, ever. Depth limited to 64 nodes. Fast updates, window queries and kNN queries. Scales very well with large datasets (10M+) and prefers clustered data over evenly distributed ... [More] data. PDFs with a description can be found in the source code. [Less]
