A probabilistic template-based approach to discovering repetitive patterns in broadcast videos

Peng Wang, Zhi-Qiang Liu, Shi-Qiang Yang
2005 Proceedings of the 13th annual ACM international conference on Multimedia - MULTIMEDIA '05  
Finally, we verify each probabilistic template by measuring the similarities between the video subsegments and the template. Evaluations on various sports videos show promising results.  ...  There are usually repetitive sub-segments in broadcast videos, which may be associated with high-level concepts or events, e.g., news footage, repeated scores in basketball.  ...  This has an added benefit: the system is more tolerant of classification errors resulted from video decomposition and symbolization.  ...
