Supervised classification for video shot segmentation
نویسندگان
چکیده
In this paper, we explore supervised classification methods for video shot segmentation. We transform the temporal segmentation problem into a multi-class categorization issue. This approach provides a uniform framework for using different kinds of features extracted from the video and for detecting various types of shot boundaries. The approach utilizes manual labeled training data and a simple classification structure, which eliminates arbitrary thresholds and achieves more reliable estimation than previous threshold-based methods. Contrastive experiments on 13 videos (~4 hours) show excellent performance on the 2001 TREC Video Track Shot Classification Task in terms of precision and recall.

Semantic Shot Classification in Sports Video
In this paper, we present a unified framework for semantic shot classification in sports videos. Unlike previous approaches, which focus on clustering by aggregating shots with similar low-level features, the proposed scheme makes use of domain knowledge of specific sport to perform a top-down video shot classification, including identification of video shot classes for each sport, and supervis...
متن کاملCombining Audio-Based and Video-Based Shot Classification Systems for News Videos Segmentation
In this paper we propose an innovative combination strategy for a system using video and audio stream of a news video to automatically segment it into stories. In our approach, the segmentation is performed in two steps: first, shots are classified by combining three different anchor shot detection algorithms using video information only. Then, the shot classification is improved by using a nov...
متن کاملA Formal Study of Video Segmentation
Video scene segmentation is the first step towards automatic video annotation. For efficient video indexing and retrieval first step is to divide the video into shots and then classify the similar shots into scenes. In this paper we have discussed some existing algorithms for shot boundary detection, key frame extraction and classification of similar shots into scenes. The task of video segment...
متن کاملThe Segmentation and Classification of Story Boundaries in News Video
The segmentation and classification of news video into single-story semantic units is a challenging problem. This research proposes a two-level, multi-modal framework to tackle this problem. The video is analyzed at the shot and story unit (or scene) levels using a variety of features and techniques. At the shot level, we employ a Decision Tree to classify the shot into one of 13 pre-defined ca...
