Query: Learning from Multiple Sources for Video Summarisation   Many visual surveillance tasks, e.g.video summarisation, is conventionally
accomplished through analysing imagerybased features. Relying solely on visual
cues for public surveillance video understanding is unreliable, since visual
observations obtained from public space CCTV video data are often not
sufficiently trustworthy and events of interest can be subtle. On the other
hand, non-visual data sources such as weather reports and traffic sensory
signals are readily accessible but are not explored jointly to complement
visual data for video content analysis and summarisation. In this paper, we
present a novel unsupervised framework to learn jointly from both visual and
independently-drawn non-visual data sources for discovering meaningful latent
structure of surveillance video data. In particular, we investigate ways to
cope with discrepant dimension and representation whist associating these
heterogeneous data sources, and derive effective mechanism to tolerate with
missing and incomplete data from different sources. We show that the proposed
multi-source learning framework not only achieves better video content
clustering than state-of-the-art methods, but also is capable of accurately
inferring missing non-visual semantics from previously unseen videos. In
addition, a comprehensive user study is conducted to validate the quality of
video summarisation generated using the proposed multi-source model.
