本文介绍了一种新的融合范例，该范例利用任何外部函数对分割的输入层次结构的轮廓进行重新排序。地面实况分区、标记、数值函数和其他附加源用于获取新的重新排序的层次结构。这种转换有助于以不同的方式组合集合、函数和分区，从而形成分区的层次结构。这个结果被证明是一个格子，其下确界操作是约旦网开孔。应用程序通过伯克利数据集的层次结构和基本事实进行了演示。实验包括通过接近真实情况进行层次结构转换、两个层次结构的融合、测量所述转换产生的结构变化。我们还演示了如何使用 Jordan 曲线的内在属性（例如曲率）在分区轮廓上产生方向开口并重新排序层次结构，特别是四叉树分区上的 L 开口。
This paper introduces a new fusion paradigm that reorders the contours of an input hierarchy of segmentations utilizing any external function. Ground truth partitions, markers, numerical functions, and other additional sources are used to obtain a new reordered hierarchy. This transformation aids in combining sets, functions, and partitions in different ways, resulting in a hierarchy of partitions. This result is shown to be a lattice whose infimum operation is theJordan net opening. Applications are demonstrated over hierarchies and ground truths from the Berkeley dataset. Experiments include hierarchy transformation by proximity to ground truth, fusion of two hierarchies, measuring structural changes produced by said transformations. We also demonstrate how intrinsic properties of the Jordan curves, like curvature, can be used to produce directional openings on contours of the partitions and reorder the hierarchy, in particular the L-opening over Quadtree partitions.
