摘要

我们描述了一种新的基于外观的视频对象提取和表示方案。用于视频对象提取的跟踪算法基于一种新的特征空间更新方案。我们提出了一种基于外观层次结构的视频对象组织方案。采用一种新的基于奇异值分解的特征空间合并算法构建基于外观的层次结构。层次结构支持近似的查询解析。在大量的视频序列上进行的实验已经产生了令人鼓舞的结果。

An appearance based approach for video object extraction and representation
We describe a novel appearance based scheme for extraction and representation of video objects. The tracking algorithm used for video object extraction is based upon a new eigen-space update scheme. We propose a scheme for organisation of video objects in an appearance based hierarchy. The appearance based hierarchy is constructed using a new SVD based eigen-space merging algorithm. The hierarchy enables approximate query resolution. Experiments performed on a large number of video sequences have yielded promising results.
