From Pixels to Perception: Beyond Napoleon’s White Horse - Seminario

Dettagli

Il giorno 4 maggio alle ore 16:30 presso l'Aula Magna di Ingegneria, il Dr. Ricardo Marroquim terra' un seminario dal titolo   "From Pixels to Perception: Beyond Napoleon’s White Horse".

Siete tutti invitati a partecipare.

Abstract

"What was the colour of Napoleon’s white horse?" This classic riddle highlights a fundamental challenge in visual computing: we cannot truly define colour without accounting for the entire environment: the scene, the light, and the observer. In this seminar, I will explore the transition from isolating the physical properties of a material to the complex, contextual reality of human-centric visualization.

The presentation traces a research trajectory from the development of innovative, low-cost digitization strategies for Cultural Heritage at CNR-Pisa and in Brazil, to current work at TU Delft on the high-fidelity modelling of material appearance through advanced BRDF and microsurface acquisition. We will examine the perceptual intricacies that arise when moving from pure radiometry to the "human-in-the-loop" challenges of immersive displays. I will then showcase a series of recent human-centric XR-related research such as Social & Infrastructure, Healthcare, and Education.
