Homography patches dataset
This repository contains the code for evaluating feature descriptors
HPatches dataset. For more information on the methods and the
evaluation protocols please check .
We provide two implementations for computing results on the HPatches
dataset, one in
python and one in
Getting the dataset
The data required for the benchmarks are saved in the
and are shared between the two implementations.
To download the
HPatches image dataset, run the provided shell script
sh download.sh hpatches
To download the pre-computed files of a baseline descriptor
X on the
HPatches dataset, run the provided
download.sh script with the
descr X argument.
To see a list of all the currently available descriptor file results,
run scipt with only the
sh download.sh descr # prints all the currently available baseline pre-computed descriptors sh download.sh descr sift # downloads the pre-computed descriptors for sift
HPatches dataset is saved on
./data/hpatches-release and the pre-computed descriptor files are saved on
After download, the folder
../data/hpatches-release contains all the
patches from the 116 sequences. The sequence folders are named with
the following convention
i_X: patches extracted from image sequences with illumination changes
v_X: patches extracted from image sequences with viewpoint changes
For each image sequence, we provide a set of reference patches
ref.png. For the remaining 5 images in the sequence, we provide
three patch sets
tK.png, containing the
corresponding patches from
ref.png as found in the
K-th image with
increasing amounts of geometric noise (
Please see the patch extraction method details for more information about the extraction process.
