Video　summarization　enables　convenient　and　efficient　management　of　large　volume　of　visual　data.　However,　most　existing　summarization　approaches　are　based　on　either　the　pixel　domain　information　or　conventional　video　compression　standards.　As　the　most　recent　and　popular　international　video　coding　standard,　H.264/AVC　adopts　a　number　of　advanced　techniques　and　brings　not　only　opportunities　but　also　challenges　to　video　summarization.　In　this　paper,　we　propose　a　real-time　image　storyboard　generation　algorithm　for　H.264/AVC　compressed　videos　by　using　both　compressed　domain　and　pixel　domain　information　jointly　and　adaptively.　This　algorithm　extracts　compressed　domain　information　for　visual　content　representation,　video　structuring　and　candidate　representative　frame　selection.　By　fusing　both　compressed　domain　and　pixel　domain　information,　the　redundancy　in　the　candidate　representative　frames　is　further　reduced.　Our　experimental　results　show　that　the　proposed　algorithm　can　efficiently　produce　image　storyboards　conforming　to　human　interpretation　of　the　essential　content　in　generic　videos.　©　2012　IEEE.
