Tracking users' capture intention: a novel complementary view for home video content analysis

In this paper, we present a novel view to home video content analysis, which aims at tracking the capture intention of camcorder users. Based on the study of intention mechanism in psychology, a set of domain-specific capture intention concepts are defined. A comprehensive and extensible scheme consisting of video structuring, intention oriented feature analysis, as well as intention unit segmentation and classification is proposed to mine the users' capture intention. Experiments were carried on home video sequences of 90 hours in total, taken by 16 persons in recent 20 years. Both the user study and objective evaluations indicate that our proposed intention-based approach is an effective complement to existing home video content analysis schemes.

在本文中，我们提出了一种家庭视频内容分析的新视角，其目的在于追踪摄像机用户的拍摄意图。基于对心理学中意图机制的研究，定义了一组特定领域的拍摄意图概念。提出了一个由视频结构化、面向意图的特征分析以及意图单元分割和分类组成的全面且可扩展的方案，以挖掘用户的拍摄意图。对总共90小时、由16人在近20年拍摄的家庭视频序列进行了实验。用户研究和客观评估都表明，我们提出的基于意图的方法是对现有家庭视频内容分析方案的有效补充。
