| Abstract: | An advanced content based news video browsing and querying system, NewsBR, is proposed in this work. The system is built on high accuracy news story segmentation and topic caption text extraction. Its main features include category based news story browsing, key frame based video abstract and keyword based news story querying. In this paper, news story segmentation and topic caption text extraction, as well as content based video browsing and querying, are addressed in detail. The system is helpful and effective for the overall understanding of the news video content. |
