Title: Tactics Analysis on NBA Broadcast Videos

Abstract:
Basketball video analysis has many commercial applications and has attracted great
attention in recent years. With the assistance of advanced object-detection and
tracking techniques developed in the past few years, efficient and effective player
tracking and identification have become a reality. Under these circumstances, to
develop a fully automatic basketball video analysis system that can analyze the
interaction among players or the scoring process becomes possible. An automatic
basketball video analysis system has many potential applications. For example, it
can provide better services by automatically generating some video segments that
highlight star players. In addition, the coaching staff of a team can employ such
techniques to calculate the statistics of players, to analyze the strength and weakness
of competitors, and to review the team itself. In this talk, I will introduce the
developed system in details, from player detection and tracking, to tactics analysis
based on the spatio-temporal trajectories of the five offensive players.
