SPOCA-suite：一个用于提取和跟踪EUV图像上活动区域和冠状孔的软件
The SPOCA-suite: a software for extraction and tracking of Active Regions and Coronal Holes on EUV images
摘要：
EUV成像仪观测到的活动区域和冕洞的精确定位和表征对于广泛的太阳和太阳物理学研究至关重要。我们描述了一个分割程序，SPOCA套件，产生目录的活动区域（AR）和冠状孔（CH）的SDO-AIA图像。该方法建立在我们以前的工作“空间可能性聚类算法”（SPOCA），并大大提高了它在几个方面。SPOCA套件几乎实时地应用于AIA档案，并每四小时产生一次太阳物理事件知识库（HEK）的AR和CH目录。我们给出了一个说明使用SPOCA的CH填充因子的测定。本报告旨在作为战略行动和能力建设成果用户的参考指南。
英文摘要：
Precise localisation and characterization of active regions and coronal holes as observed by EUV imagers are crucial for a wide range of solar and helio-physics studies. We describe a segmentation procedure, the SPOCA-suite, that produces catalogs of Active Regions (AR) and Coronal Holes (CH) on SDO-AIA images. The method builds upon our previous work on 'Spatial Possibilistic Clustering Algorithm' (SPOCA) and substantially improve it in several ways. The SPOCA-suite is applied in near real time on AIA archive and produces entries into the AR and CH catalogs of the Heliophysics Event Knowledgebase (HEK) every four hours. We give an illustration of the use of SPOCA for determination of the CH filling factors. This reports is intended as a reference guide for the users of SPoCA output.
