“…Nevertheless, the tracking task becomes very complex because the dynamic conditions of the game brings about drastic changes of positions and interactions between players, which difficult the construction of models capable of recognizing and discovering behaviors of teams playing soccer matches (Lattner et al, 2005). In (Ramos & Ayanegui, 2008b), we proposed a model able to manage the constant changes occurring in the game, which consists in building topological structures based on triangular planar graphs. Thus, based on this model tactical behavior patterns have been discovered and tracked in spite of the dynamic conditions.…”
