About the talk:
What can a reused photograph tell us about political persuasion? And what can a blurry exhibition photograph reveal about a display that no longer exists? This lecture introduces digital historical forensics, an approach that brings computer vision into conversation with close visual reading and archival research. Drawing on wartime Chinese pictorials and photographic exhibitions, I examine two related problems. First, tracing photographs across issues of the Jinchaji Pictorial reveals how cropping, recaptioning, and republication transformed their historical meanings. Second, identifying tiny photographs within surviving exhibition views helps reconstruct lost displays and the narratives they conveyed. In both cases, computational methods search large, fragmented collections not simply to detect patterns, but to recover small differences and overlooked connections. The broader question is how machine-assisted discoveries become historical evidence, and what interpretive work remains for the historian.
About the speaker:
Lin Du is Assistant Professor and Presidential Young Scholar jointly appointed in the Department of Chinese History and Culture and the Division of Artificial Intelligence and the Humanities at The Hong Kong Polytechnic University. Her research brings together visual and media history, digital humanities, and computational methods, with a particular interest in how computer vision can recover connections among historical images and reconstruct their changing contexts of circulation and interpretation. Her work has appeared in the ACM Journal on Computing and Cultural Heritage and the Journal of Chinese Cinemas. Before joining PolyU, she was Assistant Professor at the National University of Singapore. She received her PhD from UCLA.
