摘要
为了克服现有视频摘要技术难于适应新的应用环境的问题,本文提出了基于“实体-描述-效用”模型视频摘要技术。该模型利用实体生成描述,然后由描述得到效用函数,最后在效用函数的基础上获取摘要。本文还利用这一模型对新闻视频摘要进行了测试,取得了较好的实验结果。
In order to overcome the problem that most of the current video abstract technologies are difficultly suitable to new application environments, we present the video summarization technology based on the “Entities- Description- Utilities” model in this paper. In the model, we first use entities to produce description, then compute utility functions according to the description, and finally acquire video abstract based on the utilities. In this paper, we apply the model to testing news video summarization and get good experimental results.
