flann: flann (Fast Library for Approximate Nearest Neighbors) flann: flann: FLANN is a library for performing fast approximate flann: nearest neighbor searches in high dimensional spaces. It contains a flann: collection of algorithms we found to work best for nearest neighbor flann: search and a system for automatically choosing the best algorithm and flann: optimum parameters depending on the dataset. flann: flann: Homepage: http://www.cs.ubc.ca/~mariusm/index.php/FLANN/FLANN flann: flann:
