Naming faces in films using hypergraph matching
In this paper, we aim to address the problem of naming faces in feature-length films using video and film script. Different from the state-of-the-art methods on naming faces in the videos, most of which used a local matching between a visible face and one of the names extracted from the local video transcript, we use a global matching between names and faces as it is not easy to obtain enough local name cues in the films. In the video, we cluster the faces into groups corresponding to characters and build a face network according to face co-occurrence relationship. Similarly in the film script, a name network is also built according to name cooccurrence relationship. The vertices of the two networks are finally matched by a hypergraph matching method. Experiments are conducted on five feature-length films and give encouraging results.
