WILDTRACK pedestrian detection dataset

WILDTRACK is a dataset of video recordings of thousands of students, faculty and others to-ing and fro-ing 'in the wild' outside the main building at ETH University, Zurich. 

Developed by École Polytechnique Fédérale de Lausanne and ETH University researchers in Switzerland, the dataset comprises seven 35 minute videos captured by seven high-definition GoPro cameras during good weather conditions

The videos were subsequently annotated to mark the positions of people in each frame and informed research (pdf) papers on the project.

Developer: École Polytechnique Fédérale de Lausanne; ETH University
Country: Switzerland
Sector: Technology; Research/academia
Purpose: Improve pedestrian detection
Technology: Dataset; Pedestrian detection; Computer vision; Pattern recognition
Issue: Privacy; Surveillance; Dual/multi-use
Transparency: Privacy


While notices were placed underneath each of the cameras, the recordings were largely made without the knowledge or consent of those captured due to their size and inconspicuous nature.

As researcher Adam Harvey notes in his exposing.ai project, this means students will be used as training data and have almost no recourse for redaction as the data is shared, copied, and manipulated across multiple legal jurisdictions. 

Drone, retail surveillance

WILDTRACK has been made openly available for any type of research, with potential applications envisaged (pdf) by the researchers including security, surveillance, remote person identification, robotics, autonomous driving, and crowdsourcing. 

Published research studies reveal that WILDTRACK has been used by a range of academic and commercial entities such as the Nanjing University of Aeronautics (NUAA), the University of Leicester, Microsoft, and Wormplex AI to improve drone and retail surveillance.

Harvey notes that 'NUAA has produced over 40 unmanned aerial vehicles (UAVs) for China, most of which are small or micro sized UAVs with consumer or industrial surveillance capabilities ... [with] a limited number .. made specifically for military reconnaissance.'
