An unofficial PyTorch implementation of MPIIGaze and MPIIFaceGaze

MIT License GitHub stars

Here is a demo program. See also this repo.

Requirements

pip install -r requirements.txt

Download the dataset and preprocess it

MPIIGaze

bash scripts/download_mpiigaze_dataset.sh
python tools/preprocess_mpiigaze.py --dataset datasets/MPIIGaze -o datasets/

MPIIFaceGaze

bash scripts/download_mpiifacegaze_dataset.sh
python tools/preprocess_mpiifacegaze.py --dataset datasets/MPIIFaceGaze_normalized -o datasets/

Usage

This repository uses YACS for configuration management. Default parameters are specified in gaze_estimation/config/defaults.py (which is not supposed to be modified directly). You can overwrite those default parameters using a YAML file like configs/mpiigaze/lenet_train.yaml.

Training and Evaluation

By running the following code, you can train a model using all the data except the person with ID 0, and run test on that person.

python train.py --config configs/mpiigaze/lenet_train.yaml
python evaluate.py --config configs/mpiigaze/lenet_eval.yaml

Using scripts/run_all_mpiigaze_lenet.sh and scripts/run_all_mpiigaze_resnet_preact.sh, you can run all training and evaluation for LeNet and ResNet-8 with default parameters.

Results

MPIIGaze

Model Mean Test Angle Error [degree] Training Time
LeNet 6.52 3.5 s/epoch
ResNet-preact-8 5.73 7 s/epoch

The training time is the value when using GTX 1080Ti.

MPIIFaceGaze

Model Mean Test Angle Error [degree] Training Time
AlexNet 5.06 135 s/epoch
ResNet-14 4.83 62 s/epoch

The training time is the value when using GTX 1080Ti.

Demo

This demo program runs gaze estimation on the video from a webcam.

  1. Download the dlib pretrained model for landmark detection.

    bash scripts/download_dlib_model.sh
  2. Calibrate the camera.

    Save the calibration result in the same format as the sample file data/calib/sample_params.yaml.

  3. Run demo.

    Specify the model path and the path of the camera calibration results in the configuration file as in configs/demo_mpiigaze_resnet.yaml.

    python demo.py --config configs/demo_mpiigaze_resnet.yaml
