Tennis video’s serve events were detected. In other words, athletes area were obtained to calculate particle of athletes area and particle shift in adjacent frame by using background subtraction algorithm. And then tennis video’s serve events were inferred, according to specific constraints on serve, through establishing ontology and setting SWRL rules.
