区间卷分解器(IVD)是用于将整个卷分解成区间卷的接口，每个区间卷都具有独特的卷特征。IVD的优点是，它允许我们通过从外到内剥离间隔卷来查看卷的内部，不仅是交互的，而且是自动的。这是由于对分解的区间体积的嵌套结构进行了严格的分析，通过构建根据标量场描绘等值面转变的水平集图来实现。介绍了一种计算这类水平集图的稳健算法，以便通过将局部区间体积组合成有限数量的全局组来提取体积中的重要结构。演示了几个医学和模拟数据集的分解示例，从而使当前界面有效地遍历了体积的底层结构。
The Interval Volume Decomposer (IVD) is an interface for decomposing an entire volume into interval volumes each of which characterizes a distinctive volume feature. The advantage of the IVD is that it allows us to look inside the volume by peeling interval volumes from outside to inside not only interactively but also automatically. This is achieved due to the rigorous analysis of nested structures of the decomposed interval volumes by constructing a level-set graph that delineates isosurface transitions according to the scalar field. A robust algorithm for computing such level-set graphs is introduced in order to extract significant structures in the volume by putting together local interval volumes into a finite number of global groups. Several decomposition examples of medical and simulated datasets are demonstrated so that the present interface effectively traverses the underlying structures of the volume.
