PUC Minas and IRISA at Multimodal Person Discovery

Abstract : This paper describes the systems developed by PUC Minas and IRISA for the person discovery task at MediaEval 2016. We adopt a graph-based representation and investigate two tag-propagation approaches to associate overlays co-occurring with some speaking faces to other visually or audiovisually similar speaking faces. Given a video, we first build a graph from the detected speaking faces (nodes) and their audiovisual similarities (edges). Each node is associated to its co-occurring overlays (tags) when they exist. Then, we consider two tag-propagation approaches, respectively based on a random walk strategy and on Kruskal's algorithm.
