The algorithms are able to extract characteristics of specific event types(e.g. a goal in a football match) from video streams. The timestamp of an eventcan also be identified to provide a chronological list of events occuring in avideoParent ---Extensions ---Includes UC-230430Scope Event recognitionActor(s) IKS ServiceGoal The event data contained in the video stream is successfully extracted.Trigger The event recognition service is performed and the video stream is analyzed.Preconditions1. The video stream is available in an appropriate format.Minimal Postconditions1. The service provides a status response to the user.Success Postconditions1. The event data has successfully been extracted and can be processed by therecognition engine.Main Flow1. Load video stream to analysis engine© IKS Consortium2010
