Dataset Preparation

This page provides the instructions for dataset preparation on existing benchmarks, include

1. Download Datasets

Please download the datasets from the official websites. It is recommended to symlink the root of the datasets to $MMTRACKING/data.

1.1 Video Object Detection

  • For the training and testing of video object detection task, only ILSVRC dataset is needed.

  • The Lists under ILSVRC contains the txt files from here.

1.2 Multiple Object Tracking

  • For the training and testing of multi object tracking task, one of the MOT Challenge datasets (e.g. MOT17, TAO and DanceTrack) is needed. CrowdHuman and LVIS can be served as complementary datasets.

  • The annotations under tao contains the official annotations from here.

  • The annotations under lvis contains the official annotations of lvis-v0.5 which can be downloaded according to here. The synset mapping file coco_to_lvis_synset.json used in ./tools/convert_datasets/tao/merge_coco_with_lvis.py script can be found here.

1.3 Single Object Tracking

  • For the training and testing of single object tracking task, the MSCOCO, ILSVRC, LaSOT, UAV123, TrackingNet, OTB100, GOT10k and VOT2018 datasets are needed.

  • For OTB100 dataset, you don't need to download the dataset from the official website manually, since we provide a script to download it.

# download OTB100 dataset by web crawling
python ./tools/convert_datasets/otb100/download_otb100.py -o ./data/otb100/zips -p 8
  • For VOT2018, we use the official download script.
# download VOT2018 dataset by web crawling
python ./tools/convert_datasets/vot/download_vot.py --dataset vot2018 --save_path ./data/vot2018/data

1.4 Video Instance Segmentation

  • For the training and testing of video instance segmetatioon task, only one of YouTube-VIS datasets (e.g. YouTube-VIS 2019) is needed.

1.5 Data Structure

If your folder structure is different from the following, you may need to change the corresponding paths in config files.

2. Convert Annotations

We use CocoVID to maintain all datasets in this codebase. In this case, you need to convert the official annotations to this style. We provide scripts and the usages are as following:

# ImageNet DET
python ./tools/convert_datasets/ilsvrc/imagenet2coco_det.py -i ./data/ILSVRC -o ./data/ILSVRC/annotations

# ImageNet VID
python ./tools/convert_datasets/ilsvrc/imagenet2coco_vid.py -i ./data/ILSVRC -o ./data/ILSVRC/annotations

# MOT17
# The processing of other MOT Challenge dataset is the same as MOT17
python ./tools/convert_datasets/mot/mot2coco.py -i ./data/MOT17/ -o ./data/MOT17/annotations --split-train --convert-det
python ./tools/convert_datasets/mot/mot2reid.py -i ./data/MOT17/ -o ./data/MOT17/reid --val-split 0.2 --vis-threshold 0.3

# DanceTrack
python ./tools/convert_datasets/dancetrack/dancetrack2coco.py -i ./data/DanceTrack -o ./data/DanceTrack/annotations

# CrowdHuman

# LVIS
# Merge annotations from LVIS and COCO for training QDTrack
python ./tools/convert_datasets/tao/merge_coco_with_lvis.py --lvis ./data/lvis/annotations/lvis_v0.5_train.json --coco ./data/coco/annotations/instances_train2017.json --mapping ./data/lvis/annotations/coco_to_lvis_synset.json --output-json ./data/lvis/annotations/lvisv0.5+coco_train.json

# TAO
# Generate filtered json file for QDTrack
python ./tools/convert_datasets/tao/tao2coco.py -i ./data/tao/annotations --filter-classes

# LaSOT
python ./tools/convert_datasets/lasot/gen_lasot_infos.py -i ./data/lasot/LaSOTBenchmark -o ./data/lasot/annotations

# UAV123
# download annotations
# due to the annotations of all videos in UAV123 are inconsistent, we just download the information file generated in advance.
wget https://download.openmmlab.com/mmtracking/data/uav123_infos.txt -P data/uav123/annotations

# TrackingNet
# unzip files in 'data/trackingnet/*.zip'
bash ./tools/convert_datasets/trackingnet/unzip_trackingnet.sh ./data/trackingnet

The folder of annotations in ILSVRC

There are 3 JSON files in data/ILSVRC/annotations:

imagenet_det_30plus1cls.json: JSON file contains the annotations information of the training set in ImageNet DET dataset. The 30 in 30plus1cls denotes the overlapped 30 categories in ImageNet VID dataset, and the 1cls means we take the other 170 categories in ImageNet DET dataset as a category, named as other_categeries.

imagenet_vid_train.json: JSON file contains the annotations information of the training set in ImageNet VID dataset.

imagenet_vid_val.json: JSON file contains the annotations information of the validation set in ImageNet VID dataset.

The folder of annotations and reid in MOT15/MOT16/MOT17/MOT20

We take MOT17 dataset as examples, the other datasets share similar structure.

There are 8 JSON files in data/MOT17/annotations:

train_cocoformat.json: JSON file contains the annotations information of the training set in MOT17 dataset.

train_detections.pkl: Pickle file contains the public detections of the training set in MOT17 dataset.

test_cocoformat.json: JSON file contains the annotations information of the testing set in MOT17 dataset.

test_detections.pkl: Pickle file contains the public detections of the testing set in MOT17 dataset.

half-train_cocoformat.json, half-train_detections.pkl, half-val_cocoformat.jsonand half-val_detections.pkl share similar meaning with train_cocoformat.json and train_detections.pkl. The half means we split each video in the training set into half. The first half videos are denoted as half-train set, and the second half videos are denoted ashalf-val set.

The structure of data/MOT17/reid is as follows:

reid
├── imgs
│   ├── MOT17-02-FRCNN_000002
│   │   ├── 000000.jpg
│   │   ├── 000001.jpg
│   │   ├── ...
│   ├── MOT17-02-FRCNN_000003
│   │   ├── 000000.jpg
│   │   ├── 000001.jpg
│   │   ├── ...
├── meta
│   ├── train_80.txt
│   ├── val_20.txt

The 80 in train_80.txt means the proportion of the training dataset to the whole ReID dataset is 80%. While the proportion of the validation dataset is 20%.

For training, we provide a annotation list train_80.txt. Each line of the list contains a filename and its corresponding ground-truth labels. The format is as follows:

MOT17-05-FRCNN_000110/000018.jpg 0
MOT17-13-FRCNN_000146/000014.jpg 1
MOT17-05-FRCNN_000088/000004.jpg 2
MOT17-02-FRCNN_000009/000081.jpg 3

MOT17-05-FRCNN_000110 denotes the 110-th person in MOT17-05-FRCNN video.

For validation, The annotation list val_20.txt remains the same as format above.

Images in reid/imgs are cropped from raw images in MOT17/train by the corresponding gt.txt. The value of ground-truth labels should fall in range [0, num_classes - 1].

The folder of annotations in crowdhuman

There are 2 JSON files in data/crowdhuman/annotations:

crowdhuman_train.json: JSON file contains the annotations information of the training set in CrowdHuman dataset. crowdhuman_val.json: JSON file contains the annotations information of the validation set in CrowdHuman dataset.

The folder of annotations in lvis

There are 8 JSON files in data/lvis/annotations

coco_to_lvis_synset.json: JSON file contains the mapping relationship between COCO and LVIS categories.
