This is the official codebase of the pupillometry system paper PupilSense: Detection of Depressive Episodes Through Pupillary Response in the Wild, accepted by 2024 International Conference on Activity and Behavior Computing.
The data collection app paper accepted by ACM MobileHCI (2024), titled FacePsy: An Open-Source Affective Mobile Sensing System -- Analyzing Facial Behavior and Head Gesture for Depression Detection in Naturalistic Settings. GitHub is coming soon!
Our work mood detection using pupillary response got accepted at IEEE BSN 2024, titled MoodPupilar: Predicting Mood Through Smartphone Detected Pupillary Responses in Naturalistic Settings.
PupilSense is a deep learning-based pupillometry system. It uses eye images collected from smartphones for research in the behavior modeling domain.
The accompanying data collection app will be released soon for the research community.
Follow these steps to set up the project:
(1) Clone the repository: git clone https://github.com/stevenshci/PupilSense.git
(2) Navigate to the project directory: cd PupilSense
(3) Install the required packages: pip install -r requirements.txt
After you install the required packages, you can just run the setup.sh script to set up the project environment:
source setup.sh
This project uses a custom dataset of eye images for training and evaluation. The dataset should be organized in the following structure:
dataset/
├── train/
│ │── image1.png
│ │── image2.png
│ └── ...
|
│── train_data.json
│
└── test/
│ ├── image1.png
│ ├── image2.png
│ └── ...
|
└── test_data.json
Note: The annotations(test_data.json, train_data.json) should be in COCO format, with the pupil and iris regions labeled as separate categories.
To annotate the dataset, use tools like MakeSense.ai, Roboflow, Labelbox, LabelImg, or VIA to label pupil and iris regions on the images. Export these annotations in the COCO format, which should include necessary details for images, annotations, and categories.
The COCO format is a standard for object detection/segmentation tasks and is widely supported by many libraries and tools in the computer vision community.
To fine-tune the Detectron2 model on your dataset, run the following command:
python scripts/finetune.py
To test your images on a batch of images on the trained model:
python scripts/inference.py
Our fine-tuned Detectron2 model achieves accurate pupil and iris segmentation on eye images captured in naturalistic environments.

The model robustly segments the pupil and iris regions in diverse real-world conditions, including varying lighting, eye positions, and backgrounds.
This capability enables practical applications in biometrics, human-computer interaction, and medical imaging, where precise segmentation in naturalistic settings is crucial.
