Suppose you want to store the reid data in a directory called "path/to/reid-data/", you need to specify the ``root`` as *root='path/to/reid-data/'* when initializing ``DataManager``. Below we use ``$REID`` to denote "path/to/reid-data".
Dataset with a :math:`\dagger` symbol means that the process is automated, so you can directly call the dataset in ``DataManager`` (which automatically downloads the dataset and organizes the data structure). However, we also provide a way below to help the manual setup in case the automation fails.
You are suggested to use the provided names for dataset folders such as "market1501" for Market1501 and "dukemtmcreid" for DukeMTMC-reID when doing the manual setup, otherwise you need to modify the source code accordingly (i.e. the ``dataset_dir`` attribute).
Some download links provided by the original authors might not work. You can email `Kaiyang Zhou <https://kaiyangzhou.github.io/>`_ to reqeust new links. Please do provide your full name, institution, and purpose of using the data in the email (best use your work email address).
- Create a directory named "market1501" under ``$REID``.
- Download the dataset to "market1501" from http://www.liangzheng.org/Project/project_reid.html and extract the files.
- The data structure should look like
..code-block:: none
market1501/
Market-1501-v15.09.15/
query/
bounding_box_train/
bounding_box_test/
- To use the extra 500K distractors (i.e. Market1501 + 500K), go to the **Market-1501+500k Dataset** section at http://www.liangzheng.org/Project/project_reid.html, download the zip file "distractors_500k.zip" and extract it under "market1501/Market-1501-v15.09.15". The argument to use these 500K distrctors is ``market1501_500k`` in ``ImageDataManager``.
CUHK03 (``cuhk03``)
^^^^^^^^^^^^^^^^^^^^^
- Create a folder named "cuhk03" under ``$REID``.
- Download the dataset to "cuhk03/" from http://www.ee.cuhk.edu.hk/~xgwang/CUHK_identification.html and extract "cuhk03_release.zip", resulting in "cuhk03/cuhk03_release/".
- Download the new split (767/700) from `person-re-ranking <https://github.com/zhunzhong07/person-re-ranking/tree/master/evaluation/data/CUHK03>`_. What you need are "cuhk03_new_protocol_config_detected.mat" and "cuhk03_new_protocol_config_labeled.mat". Put these two mat files under "cuhk03/".
- The data structure should look like
..code-block:: none
cuhk03/
cuhk03_release/
cuhk03_new_protocol_config_detected.mat
cuhk03_new_protocol_config_labeled.mat
- In the default mode, we load data using the new split (767/700). If you wanna use the original (20) splits (1367/100), please set ``cuhk03_classic_split`` to True in ``ImageDataManager``. As the CMC is computed differently from Market1501 for the 1367/100 split (see `here <http://www.ee.cuhk.edu.hk/~xgwang/CUHK_identification.html>`_), you need to enable ``use_metric_cuhk03`` in ``ImageDataManager`` to activate the *single-gallery-shot* metric for fair comparison with some methods that adopt the old splits (*do not need to report mAP*). In addition, we support both *labeled* and *detected* modes. The default mode loads *detected* images. Enable ``cuhk03_labeled`` in ``ImageDataManager`` if you wanna train and test on *labeled* images.
..note::
The code will extract images in "cuhk-03.mat" and save them under "cuhk03/images_detected" and "cuhk03/images_labeled". Also, four json files will be automatically generated, i.e. "splits_classic_detected.json", "splits_classic_labeled.json", "splits_new_detected.json" and "splits_new_labeled.json". If the parent path of ``$REID`` is changed, these json files should be manually deleted. The code can automatically generate new json files to match the new path.
DukeMTMC-reID :math:`^\dagger` (``dukemtmcreid``)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- Create a directory called "dukemtmc-reid" under ``$REID``.
- Download "DukeMTMC-reID" from http://vision.cs.duke.edu/DukeMTMC/ and extract it under "dukemtmc-reid".
- The data structure should look like
..code-block:: none
dukemtmc-reid/
DukeMTMC-reID/
query/
bounding_box_train/
bounding_box_test/
...
MSMT17 (``msmt17``)
^^^^^^^^^^^^^^^^^^^^^
- Create a directory called "msmt17" under ``$REID``.
- Download the dataset from http://www.pkuvmc.com/publications/msmt17.html to "msmt17" and extract the files.
- The data structure should look like
..code-block:: none
msmt17/
MSMT17_V1/ # or MSMT17_V2
train/
test/
list_train.txt
list_query.txt
list_gallery.txt
list_val.txt
VIPeR :math:`^\dagger` (``viper``)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- The download link is http://users.soe.ucsc.edu/~manduchi/VIPeR.v1.0.zip.
- Organize the dataset in a folder named "viper" as follows
..code-block:: none
viper/
VIPeR/
cam_a/
cam_b/
GRID :math:`^\dagger` (``grid``)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- The download link is http://personal.ie.cuhk.edu.hk/~ccloy/files/datasets/underground_reid.zip.
- Organize the dataset in a folder named "grid" as follows
..code-block:: none
grid/
underground_reid/
probe/
gallery/
...
CUHK01 (``cuhk01``)
^^^^^^^^^^^^^^^^^^^^^^^^
- Create a folder named "cuhk01" under ``$REID``.
- Download "CUHK01.zip" from http://www.ee.cuhk.edu.hk/~xgwang/CUHK_identification.html and place it under "cuhk01/".
- The code can automatically extract the files, or you can do it yourself.
- The data structure should look like
..code-block:: none
cuhk01/
campus/
SenseReID (``sensereid``)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
- Create "sensereid" under ``$REID``.
- Download the dataset from this `link <https://drive.google.com/file/d/0B56OfSrVI8hubVJLTzkwV2VaOWM/view>`_ and extract it to "sensereid".
- Create a folder named "cuhksysu" under ``$REID``.
- Download the data to "cuhksysu/" from this `google drive link <https://drive.google.com/file/d/1XmiNVrfK2ZmI0ZZ2HHT80HHbDrnE4l3W/view?usp=sharing>`_.
- Download the split created by *iLIDS-VID* from `this google drive <https://drive.google.com/open?id=1qw7SI7YdIgfHetIQO7LLW4SHpL_qkieT>`_ and put it under "prid2011/". Following the standard protocol, only 178 persons whose sequences are more than a threshold are used.
