如今，从数值模拟和测量设备中已经产生了大量的体数据集。然而，分类和参考通常是人工执行的，例如测量工程师的视力或经验。目前还没有一种有效的方法来搜索体数据集之间的相似性。在本文中，我们提出了一种利用临界点图进行分类和参考的技术，该图以简单的图形表示了体数据集的特征。为此，需要高效地生成临界点图，并且需要高效地计算体数据集中的临界点。
Nowadays, a huge volume datasets has been generated from numerical simulations and measurement equipments. However the classification and reference has been usually performed manually, such as vision or experience of a measurement engineer. There still has not been revealed efficient techniques for searching similarity between volumetric datasets.In this report, we propose a technique of performing the classification and reference using the critical point graph which expresses the feature of volume datasets in the simple figure. For this purpose, critical point graphs need to be generated efficiently and it is necessary to calculate the critical point in volume datasets efficiently.
