Abstract

Discontinuities in any information bearing signal serve to represent much of the vital or interesting content in that signal. A sharp loud noise in a movie could be a gun, or something breaking. In sports like tennis, cricket or snooker/pool it would indicate a point scoring event. In both cases the discontinuity is likely to be semantically relevant without further inference being necessary, once a particular domain is adopted. This paper discusses the importance of temporal motion discontinuities in inferring events in visual media. Two particular application domains are considered: content based audio/video synchronisation and event spotting in observational Psychology.
