EVA: An Efficient System for Exploratory Video Analysis

---

Talk Info:

High-resolution, continuously-recording, and nearly-ubiquitous cameras provide great value for retrospective video analysis tasks in areas such as crime investigations and scientific research. This kind of video analysis task is often both interactive and exploratory in nature, where multiple queries are tried, aborted, refined, and re-executed in an iterative fashion. This exploratory video analysis usage model presents some unique challenges and opportunities for system optimizations. We present our ongoing work in building EVA, an efficient system for exploratory video analysis. We describe optimizations we have implemented and present some promising preliminary experimental results.
