Detection of identical events from broadcasted sports video by comparing camera works

Abstract

If identical events in a video stream can be recognized, it will become useful information for organizing the continuous media. In broadcasted sports video, there are scenes called "replay" which include important events identical to the live scenes. In this paper, we propose a new method for detection of identical events by analyzing and matching of the live and replay scenes for broadcasted video of American football. The proposed method pays attention to camera works, because we consider that the works of different cameras that track identical events may move in a similar way. The basic experimental results show that this method is effective for detection of identical events.keywords: broadcasted sports video, identical event, camera work, code sequence

Video Scene Detection Based on Recurring Motion Patterns

“…Another solution for motion based detection of identical events is introduced in [9]. Shots that correspond to one semantic event are grouped based on the camera motion during the capturing process.…”
