Tracking performance
Benchmark Evaluation
| Dataset | HOTA | IDF1 | Assa | MOTA | DetA | Weight | Results |
|---|---|---|---|---|---|---|---|
| DanceTrack | 62.3 | 63.0 | 47.2 | 92.8 | 82.5 | download | DanceTrack_Results |
| SportsMOT | 76.2 | 76.1 | 65.1 | 97.1 | 89.3 | download | SportsMOT_Results |
| MOT17 | 64.5 | 79.3 | 64.6 | 79.8 | 64.7 | download | MOT17_Results |
| MOT20 | 61.7 | 74.9 | 60.5 | 76.7 | 63.2 | download | MOT20_Results |
Results on DanceTrack test set with different detector
| Detector | HOTA | IDF1 | MOTA | FPS |
|---|---|---|---|---|
| YOLOX-S | 53.3 | 56.6 | 88.4 | 30.3 |
| YOLOX-M | 57.2 | 58.6 | 91.2 | 25.4 |
| YOLOX-L | 61.5 | 61.7 | 92.0 | 24.2 |
| YOLOX-X | 62.3 | 63.0 | 92.8 | 22.7 |
The tracking speed (including detection and tracking speed) is test on an RTX 3090 GPU. Smaller detectors can achieve higher FPS, which indicates that DiffMOT can flexibly choose different detectors for various real-world application scenarios. With YOLOX-S, the tracking speed of the entire system can reach up to 30.3 FPS.
Video demos
I. Installation.
- install torch
conda create -n diffmot python=3.9
conda activate diffmot
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2
- install other packages.
pip install -r requirement.txt
- install external dependencies.
cd external/YOLOX/
pip install -r requirements.txt && python setup.py develop
cd ../external/deep-person-reid/
pip install -r requirements.txt && python setup.py develop
cd ../external/fast_reid/
pip install -r docs/requirements.txt
II. Prepare Data.
The file structure should look like:
- DanceTrack

python mot_data_process.py
III. Model ZOO.
Detection Model
We provide some trained YOLOX weights in download for DiffMOT. Some of them are inherited from ByteTrack, DanceTrack, and MixSort.
ReID Model
Ours ReID models for MOT17/MOT20 is the same as BoT-SORT , you can download from MOT17-SBS-S50, MOT20-SBS-S50. The ReID model for DanceTrack is the same as Deep-OC-SORT, you can download from Dance-SBS-S50. The ReID model for SportsMOT is trained by ourself, you can download from Sports-SBS-S50.
Notes:
- MOT20-SBS-S50 is trained by Deep-OC-SORT, because the weight from BOT-SORT is corrupted. Refer to Issue.
- ReID models for SportsMOT is trained by ourself.
Motion Model (D$^2$MP)
Refer to models. We train on DanceTrack and MOT17/20 for 800 epochs, and train on SportsMOT for 1200 epochs.
IV. Training.
Train the detection model
- You can refer to the ByteTrack.
Train the ReID model
- You can refer to the BoT-SORT.
Train the motion model (D$^2$MP)
- Change the data_dir in config
- Train on DanceTrack, SportsMOT, and MOT17/20:
python main.py --config ./configs/dancetrack.yaml
python main.py --config ./configs/sportsmot.yaml
python main.py --config ./configs/mot.yaml
V. Tracking.
Prepare detections
- You can obtain the detections by detection_model or use the detection_results we have provided.
- Change the det_dir in config.
Prepare ReID embeddings
- We have provided the ReID embeddings.
- Change the reid_dir in config.
Track on DanceTrack
- Change the info_dir, and save_dir in config.
- High_thres is set to 0.6, low_thres is set to 0.4, w_assoc_emb is set to 2.2, and aw_param is set to 1.7.
python main.py --config ./configs/dancetrack_test.yaml
Track on SportsMOT
- Change the info_dir, and save_dir in config.
- High_thres is set to 0.6, low_thres is set to 0.4, w_assoc_emb is set to 2.0, and aw_param is set to 1.2.
python main.py --config ./configs/sportsmot_test.yaml
Track on MOT17
- Change the info_dir, and save_dir in config.
- High_thres is set to 0.6, low_thres is set to 0.1, w_assoc_emb is set to 2.2, and aw_param is set to 1.7.
python main.py --config ./configs/mot17_test.yaml
Track on MOT20
- Change the info_dir, and save_dir in config.
- High_thres is set to 0.4, low_thres is set to 0.1, w_assoc_emb is set to 2.2, and aw_param is set to 1.7.
python main.py --config ./configs/mot20_test.yaml
