Audio based soccer game summarization

This papers presents a simple and near real-time performance system for detecting highlighted events of soccer game retransmissions and generating their video summaries. The proposed detection algorithm is based on two acoustic features of the audio track: the block energy and the acoustic repetition index. To the authors' knowledge, the acoustic repetition index has not been used previously in similar applications. This index represents the correlation between a narrow acoustic section and the seconds just after and before it, in order to detect sections of audio where repetitions occur. The system has been validated on a corpus with EUFA EURO competition games, achieving good scores in goal recall.
