Modified to be python 3.x compatible
###1. Introduction
pyflann is the python bindings for FLANN - Fast Library for Approximate Nearest Neighbors.
#####Please feel free to contact me [[email protected]] if you have any questions.
###2. Install
This package uses distutils, which is the default way of installing python modules. To install in your home directory, securely run the following:
git clone https://github.com/primetang/pyflann.git
cd pyflann
[sudo] python setup.py install
Or directly through pip
to install it:
[sudo] pip install pyflann
###3. Usage
Use it just like the following code:
from pyflann import *
import numpy as np
dataset = np.array(
[[1., 1, 1, 2, 3],
[10, 10, 10, 3, 2],
[100, 100, 2, 30, 1]
])
testset = np.array(
[[1., 1, 1, 1, 1],
[90, 90, 10, 10, 1]
])
flann = FLANN()
result, dists = flann.nn(
dataset, testset, 2, algorithm="kmeans", branching=32, iterations=7, checks=16)
print result
print dists
dataset = np.random.rand(10000, 128)
testset = np.random.rand(1000, 128)
flann = FLANN()
result, dists = flann.nn(
dataset, testset, 5, algorithm="kmeans", branching=32, iterations=7, checks=16)
print result
print dists
