论文摘要

物联网(IoT)的概念现在是现实。这种范式转变引起了大量应用程序的关注,包括使用智能门铃的基于物联网的视频分析。由于其应用程序的不断增长,科学文献中存在各种努力,并且市场上有许多基于视频的门铃解决方案。但是,当代产品是定制的,提供了有限的合成性和智能门铃框架的可重复性。其次,它们是整体的且专有的,这意味着实现细节仍然对用户隐藏。我们认为,透明的设计可以极大地帮助开发智能门铃,从而在多个应用程序域中使用。 为了应对上述挑战,我们提出了一个分布式框架,以跨越边缘和云资源进行视频分析。我们调查了定制/完整系统中不同软件组件分布的权衡,在该系统中,Edge和Cloud的组件一般对其进行处理。本文评估了所提出的框架以及最新模型,并在各种指标(例如总体模型准确性,延迟,内存和CPU使用)上介绍了它们的比较分析。评估结果很好地证明了我们的直觉,表明基于AWS的方法与最先进的方法相比表现出相当高的对象检测准确性,低内存和CPU用法,但延迟较高。

The concept of the Internet of Things (IoT) is a reality now. This paradigm shift has caught everyones attention in a large class of applications, including IoT-based video analytics using smart doorbells. Due to its growing application segments, various efforts exist in scientific literature and many video-based doorbell solutions are commercially available in the market. However, contemporary offerings are bespoke, offering limited composability and reusability of a smart doorbell framework. Second, they are monolithic and proprietary, which means that the implementation details remain hidden from the users. We believe that a transparent design can greatly aid in the development of a smart doorbell, enabling its use in multiple application domains. To address the above-mentioned challenges, we propose a distributed framework to orchestrate video analytics across Edge and Cloud resources. We investigate trade-offs in the distribution of different software components over a bespoke/full system, where components over Edge and Cloud are treated generically. This paper evaluates the proposed framework as well as the state-of-the-art models and presents comparative analysis of them on various metrics (such as overall model accuracy, latency, memory, and CPU usage). The evaluation result demonstrates our intuition very well, showcasing that the AWS-based approach exhibits reasonably high object-detection accuracy, low memory, and CPU usage when compared to the state-of-the-art approaches, but high latency.
