Exploring the world through the lens of an event camera

Yesterday, April 9th, 2025, the Grupo de Tratamiento de Imágenes (GTI) successfully hosted the fifth seminar in the "Speaking in the Key of Science" series—an event that continues to establish itself as a key reference point for exploring the latest advances in Artificial Intelligence, Computer Vision, Extended Reality (XR), and other emerging fields.

The seminar, titled "Exploring the world through the lens of an event camera," was delivered by Guillermo Gallego, Professor at TU Berlin and the Einstein Center Digital Future.

During the session, Guillermo introduced us to the fascinating world of event cameras, vision sensors inspired by human perception that offer a revolutionary alternative to traditional cameras. Through a clear and detailed theoretical explanation, we learned how these sensors work, what kind of information they capture, and why they are especially valuable in scenarios where speed, dynamic range, and energy efficiency are critical. He also presented some of their cutting-edge applications in computer vision and robotics—from tracking and recognition systems to real-time motion estimation and autonomous navigation.

The practical demonstration was undoubtedly one of the seminar’s highlights. We had the chance to see an event camera in action and witness how it responds with remarkable efficiency to dynamic changes in a scene. Through several live demos, its potential to capture fast motion with impressive precision was illustrated, along with its ability to operate effectively under challenging lighting conditions, where conventional cameras often struggle.

This seminar not only deepened our understanding of event-based vision but also sparked thought-provoking discussions about the future of visual sensing technologies. As innovation continues to push the boundaries of what’s possible in computer vision and robotics, events like these are essential for fostering knowledge exchange and inspiring new research directions. We look forward to continuing this journey of exploration in the upcoming sessions of Speaking in the Key of Science.
