On Properties of Contours of Trilinear Scalar Fields

Abstract

We study properties of contour surfaces of trilinear scalar fields, and give a classification based on how many unconnected surface parts they consist of. Furthermore, we introduce the concept of the segment number of a voxel. The segment number is a threshold-independent measure which estimates how complicated the contours inside the voxel are expected to be. Finally, we give necessary and sufficient conditions for a voxel to have a segment number of 1. These conditions are applied to analyze a computer tomography data set.
