News

⚡(2024-1-8): The pre-trained pix2pixGAN on LLVIP is released Here.
⚡(2023-2-21): The annotations of a small part of images have been corrected and updated, including the annotation of some missing pedestrians, and the optimization of some imprecise annotations. The updated dataset is now available from the homepage or here. If you need the previous version of the annotations, please refer to here.
⚡(2022-5-24): We provide a toolbox for various format conversions (xml to yolov5, xml to yolov3, xml to coco)
⚡(2022-3-27): We released some raw data (unregistered image pairs and videos) for further research including image registration. Please visit homepage to get the update. (2022-3-28 We have updated the link of Baidu Yun of LLVIP raw data, the data downloaded from the new link supports decompression under windows and macos. The original link only support windows.)
⚡(2021-12-25): We released a Kaggle Community Competition "Find Person in the Dark!" based on part of LLVIP dataset. Welcome playing and having fun! Attention: only the visible-image data we uploaded in Kaggle platform is allowed to use (the infrared images in LLVIP or other external data are forbidden)
⚡(2021-11-24): Pedestrian detection models were released
⚡(2021-09-01): We have released the dataset, please visit homepage or here to get the dataset. (Note that we removed some low-quality images from the original dataset, and for this version there are 30976 images.)

Train & Test

  python main.py

Check and modify training/testing options in main.py. Before training/testing, you need to rename the images in LLVIP dataset and put them in the designated folder. We have provided a script named rename.py to rename the images and save them in the datasets or test folder. Checkpoints are saved in ./models/densefuse_gray/. To acquire complete LLVIP dataset, please visit https://bupt-ai-cz.github.io/LLVIP/.

We provide a toolbox for converting annotation files to txt files in yolov5 format.

Train
```
python train.py --img 1280 --batch 8 --epochs 200 --data LLVIP.yaml --weights yolov5l.pt --name LLVIP_export
```
See more training options in train.py. The pretrained model yolov5l.pt can be downloaded from here. The trained model will be saved in ./runs/train/LLVIP_export/weights folder.

Test
```
python val.py --data --img 1280 --weights last.pt --data LLVIP.yaml
```
Remember to put the trained model in the same folder as val.py.

Our trained model can be downloaded from here: Google-Drive-Yolov5-model or BaiduYun-Yolov5-model (code: qepr)
- Click Here for the tutorial of Yolov3 （Our trained Yolov3 model can be downloaded from here: Google-Drive-Yolov3-model or BaiduYun-Yolov3-model (code: ine5)）.
  Results
  
  We retrained and tested Yolov5l and Yolov3 on the updated dataset (30976 images).

Where AP means the average of AP at IoU threshold of 0.5 to 0.95, with an interval of 0.05.

The figure above shows the change of AP under different IoU thresholds. When the IoU threshold is higher than 0.7, the AP value drops rapidly. Besides, the infrared image highlights pedestrains and achieves a better effect than the visible image in the detection task, which not only proves the necessity of infrared images but also indicates that the performance of visible-image pedestrian detection algorithm is not good enough under low-light conditions.

We also calculated log average miss rate based on the test results and drew the miss rate-FPPI curve.
