高通量植物表型分析(HTPP)以其快速、省力、准确、无损等优点,成为一种新兴的植物性状研究技术。它在植物育种和作物管理中有着广泛的应用。然而,由此产生的海量图像数据给有效的植物性状预测和异常检测带来了挑战。本文提出了一种基于两步图像的在线检测框架,利用实时成像数据对植物单株叶面积进行监测和快速变化检测。在一定的虚警率约束下,我们的方法能够实现比一些基线方法更小的检测延迟。此外,它不需要存储所有过去的图像信息,可以实时实现。通过实际数据分析验证了该框架的有效性。
High-throughput plant phenotyping (HTPP) has become an emerging technique to study plant traits due to its fast, labor-saving, accurate and non-destructive nature. It has wide applications in plant breeding and crop management. However, the resulting massive image data has raised a challenge associated with efficient plant traits prediction and anomaly detection. In this paper, we propose a two-step image-based online detection framework for monitoring and quick change detection of the individual plant leaf area via real-time imaging data. Our proposed method is able to achieve a smaller detection delay compared with some baseline methods under some predefined false alarm rate constraint. Moreover, it does not need to store all past image information and can be implemented in real time. The efficiency of the proposed framework is validated by a real data analysis.
