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 dataset.FLANN is written in C++ and contains bindings for the following languages: C, MATLAB and Python.Documentation-------------
