At a glance

The thesis project focuses on the spatialization of visual contents (both image and video contents) by the exploitation of 3D references at large scale. Without any a priori about geolocation, the problem is tackled by the retrieval of the most similar elements in the geolocalized reference. As visual content, we consider old photographs and footages made available from cultural institutions, and as 3D reference we exploit LiDAR data mapping the French territory, made available at the country scale by the French mapping agency (IGN). This PhD thesis has the ambition to address two challenging scientific problems: on the one hand, the description, matching and indexing of 2D(+t) and 3D data in a multi-date context where the scene has evolved over time, and on the other hand, the fast retrieval in very large volumes of data. The work will be carried out within the framework of the multidisciplinary project AGAPE, which addresses the discoverability and investigation in spatial iconographic heritage, and gathers seven leading partners specialized in visual and multimodal AI, Multimedia and Human-Computer Interaction as well as in Archives, History and Media.
