This paper investigates the semantic analysis of broadcast tennis
footage. We consider the spatio-temporal behaviour of an object
in the footage as being the embodiment of a semantic event. This
object is tracked using a colour based particle filter. The video
syntax and audio features are used to help delineate the temporal
boundaries of these events. For broadcast tennis footage, the system
firstly parses the video sequence based on the geometry of the
content in view and classifies the clip as a particular view type.
The temporal behaviour of the serving player is modelled using
a HMM. As a result, each model is representative of a particular
semantic episode. Events are then summarised using a number of
