Abstract：

Motions　of　a　camera　can　reflect　certain　kinds　of　semantic　information　in　video　sequences;　therefore,　in　this　paper,　according　to　the　distant　court　shot　in　basketball　game,　we　calculate　the　motion　vector　first,　then　analyze　the　semantic　information　of　the　motion　vector,　and　finally　annotate　the　offense-defense　actions　in　games.　Experiments　are　showing　the　possibility　that　the　proposed　technique　can　annotate　the　offensedefense　semantic　actions　as　expected.　©2009　IEEE.
