3ET: Efficient Event-based Eye Tracking using a Change-Based ConvLSTM Network

This repo introduces you to how to perform pupil detection using event stream from event-based cameras. Here is our paper: 3ET: Efficient Event-based Eye Tracking using a Change-Based ConvLSTM Network, which was published at BioCAS 2023. The arxiv version: https://arxiv.org/pdf/2308.11771.pdf

Synthetic Event-based Eye Tracking dataset link (event raw data and .avi video files): Google Drive

Run steps:

1. Download the SEET dataset, and save it in a directory. i.e. /DATA/

2. cd eyetracking-convlstm

3. run process_event.py

   you can change the sequence length by setting the parameter seq

4. run convlstm-et-pytorch-event.py

Results: x, y coordinates of pupil center predictions after 28 epochs of training

Loading raw 3ET with the Tonic library 💥💥💥

We support using the Tonic library to automatically download the 3ET dataset and load the raw events and labels.

The Tonic library is a Python library for loading and processing event-based data. It is available at GitHub Repo

To install the Tonic library branch which includes the 3ET dataset loader, run the following command:

pip install tonic --pre

A minimum working example of loading the 3ET dataset is shown below:

import tonic

trainset = tonic.datasets.ThreeET_Eyetracking(save_to="./data", split='Train')

events, targets = next(iter(trainset))
