This project includes our solution for Track 4 of the 2023 AI City Challenge, Welcome to the RetailCounter GitHub repository, where we present our sophisticated deep learning-based framework that can recognize, localize, track, and count products as they traverse in front of a camera. The retail industry has been experiencing an upswing in the use of cutting-edge artificial intelligence and computer vision techniques. Among the major challenges in this domain is the development of an automated checkout system that can address the multifaceted issues that arise in real-world checkout scenarios. Our proposed framework, RetailCounter, is founded on a detect-then-track paradigm, and we apply tracking on the bounding box of the detected objects. In addition, we have integrated an automatic identification of the detection region of interest (ROI) and efficient removal of unwanted objects from the ROI. Our framework's performance is competitive, as evidenced by our F1 score of 0.8177 and the fourth-place ranking we achieved in track 4 of the 2023 AI City Challenge.

Link to downlaod our paper download

conda create --name aic23 python=3.9.0
conda activate aic23
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=11.0 -c pytorch
cd retailcounter
python -m pip install -r requirements.txt
cd ..

Note: for newer devices, such as the NVIDIA RTX 3090, you may use Pytorch 1.10 with cudatoolkit 11.3.

Download the track 4 dataset from the 2023 AI City Challenge.

If you do not want to train detector, You can download pretrain model from here and Dataset can be in AIC23_Track4_TestA.zip (or TestB) is sufficient.

export TRACK_4_DATA_ROOT={/path/to/track_4/root_dir}

For example: export TRACK_4_DATA_ROOT=/mnt/data/AIC22_Track4_TestA/Test_A

cd retailcounter
python download_pretrained_models.py --detector

Alternatively, you may train detector at your own

Run: To create Video Inpainting follow the steps from the GitHub repo mentioned below

git clone https://github.com/MCG-NKU/E2FGVI
python inpainting_process.py --video_id $TRACK_4_DATA_ROOT/video_id.txt

video_id.txt file is available in AIC22_Track4_TestA and contain video IDs and video file names (in the same directory)

Run:

python detect_ROI.py --video_id $TRACK_4_DATA_ROOT/video_id.txt

Arguments --roi_seed can be set (two values) - it specifies seed position for ROI detection (white tray) in format x y

Run:

python detect_and_create_submission.py --video_id $TRACK_4_DATA_ROOT/video_id.txt

Parameters --tracker and --img_size can be set. The values are pre-set to tracker = BYTE, img_size = 640

All scripts are set as the result was reported to AI City Challenge and no arguments must be set (only --video_id).

cd retailcounter
cp split_data.sh Track4/Train_SynData/segmentation_labels/split_data.sh
cd Track4/Train_SynData/segmentation_labels
bash split_data.sh

cd retailcounter
cp split_data.sh Track4/Train_SynData/syn_image_train/split_data.sh
cd Track4/Train_SynData/syn_image_train
bash split_data.sh

1. Download pretrained-model models without detector

python download_pretrained_models.py

2. Prepare AI City Challenge dataset as described above
3. Create dataset

python create_dataset.py --t_4_track {/path/to/AIC_Track4/Train_SynData}

4. Train detector In order to train the detector you need to follow this GitHub repo of YOLOV8 mentioned below

YOLOV8
git clone https://github.com/ultralytics/ultralytics
YOLOX
python train_detector.py  

Arguments --batch_size and --epochs can be set. Explicit values are batch_size = 16, epochs = 75.

• Instance segmentation: MMdetection
• Inpainting: VideoInpainting
• Detector: YOLOX, YOLOV8
• Trackers: SORT, DEEPSORT
