Offense-defense semantic analysis of basketball game based on motion vector

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 offense-defense semantic actions as expected.
