Optimising video summaries for mobile devices using visual attention modelling

Janko Calic, Neill Campbell
2006 Proceedings of the 2nd international conference on Mobile multimedia communications - MobiMedia '06  
In order to represent large video collections in the form of key-frame summary on small screen devices, this paper exploits methodology of the visual attention modelling and rapid serial visual presentation  ...  The system ranks importance of key-frame regions in the nal layout by exploiting visual attention modelling. A nal layout is created using an optimisation algorithm based on dynamic programming.  ...  The algorithm exploits visual attention modelling and creates visual summaries in an ecient and user centered way.  ...
