随着摄像机的激增，可扩展地捕获和搜索其数据的能力变得非常重要。通过在互联网边缘的cloudlet上执行视频分析，并仅将提取的索引信息和元数据发送到云端，可扩展性得到了提高。在这种情况下，我们描述了交互式数据探索（IDE），它是指使用可能不是任何先前索引的一部分的谓词的基于内容的人在回路的回顾性搜索。我们还描述了一种称为即时索引（JITI）的新技术，它可以提高IDE的响应时间。
As video cameras proliferate, the ability to scalably capture and search their data becomes important. Scalability is improved by performing video analytics on cloudlets at the edge of the Internet, and only shipping extracted index information and meta-data to the cloud. In this setting, we describe interactive data exploration (IDE), which refers to human-in-the-loop content-based retrospective search using predicates that may not have been part of any prior indexing. We also describe a new technique called just-in-time indexing (JITI) that improves response times in IDE.
