%description
FLANN is a library for performing fast approximate nearest neighbour
searches in high dimensional spaces. It contains a collection of
algorithms we found to work best for nearest neighbour 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.

%description -l pl.UTF-8
FLANN (Fast Library for Approximage Nearest Neighbours) to biblioteka
do wykonywania szybkich przybliżonych wyszukiwań najbliższych sąsiadów
w przestrzeniach o wielu wymiarach. Zawiera zbiór algorytmów, które
sprawdzają się najlepiej w tym zastosowaniu oraz system automatycznego
wyboru najlepszego algorytmu oraz optymalnych parametrów w zależności
od zbioru danych.

Biblioteka FLANN została napisana w C++ i zawiera dowiązania dla
następujących języków: C, MATLAB i Python.
