End-to-End Human-Gaze-Target Detection with Transformers

An unofficial PyTorch implementation of the paper "End-to-End Human-Gaze-Target Detection with Transformers".

Prerequisites

Environment and dependencies

We provide a pip requirements file to install all the dependencies. We recommend using a conda environment to install the dependencies.

# Clone project and submodules
git clone --recursive https://github.com/francescotonini/human-gaze-target-detection-transformer.git
cd human-gaze-target-detection-transformer

# Create conda environment
conda create -n human-gaze-target-detection-transformer python=3.9
conda activate human-gaze-target-detection-transformer

# Install requirements
pip install -r requirements.txt

(optional) Setup wandb

cp .env.example .env

# Add token to .env

Dataset preprocessing

The code expects that the datasets are placed under the data/ folder. You can change this by modifying the data_dir parameter in the configuration files.

cat <<EOT >> configs/local/default.yaml
# @package _global_

paths:
  data_dir: "{PATH TO DATASETS}"
EOT

The implementation requires faces annotations ("auxiliary faces", i.e. the ones not annotated by GazeFollow or VideoAttentionTarget). Therefore, you need run the following script to extract face annotations.

# GazeFollow
python scripts/gazefollow_get_aux_faces.py --dataset_path /path/to/gazefollow --subset train
python scripts/gazefollow_get_aux_faces.py --dataset_path /path/to/gazefollow --subset test

# VideoAttentionTarget
cp data/videoattentiontarget_extended/*.csv /path/to/videoattentiontarget

python scripts/videoattentiontarget_get_aux_faces.py --dataset_path /path/to/videoattentiontarget --subset train
python scripts/videoattentiontarget_get_aux_faces.py --dataset_path /path/to/videoattentiontarget --subset test

Training

We provide configuration to train on GazeFollow and VideoAttentionTarget (see configs/experiment/).

# GazeFollow
python src/train.py experiment=hgttr_gazefollow

# VideoAttentionTarget
python src/train.py experiment=hgttr_videoattentiontarget +model.net_pretraining={URL/PATH TO GAZEFOLLOW WEIGHTS}

Evaluation

The configuration files are also useful when evaluating the model.

# GazeFollow
python src/eval.py experiment=hgttr_gazefollow ckpt_path={PATH TO CHECKPOINT}
# or
python src/eval.py experiment=hgttr_gazefollow +model.net_pretraining={URL/PATH TO WEIGHTS}

# VideoAttentionTarget
python src/eval.py experiment=hgttr_videoattentiontarget ckpt_path={PATH TO CHECKPOINT}
# or
python src/eval.py experiment=hgttr_videoattentiontarget +model.net_pretraining={URL/PATH TO WEIGHTS}

Checkpoints

We provide model weights for GazeFollow at this URL and VideoAttentionTarget at this URL.
