Constructing Smooth Non-Manifold Meshes of Labeled Volumetric Datasets

B. Reitinger, A. Bornik

This paper presents a method for constructing consistent non-manifold meshes of multi-labeled volumetric datasets. This
approach is different to traditional surface reconstruction
algorithms which often only support extracting 2-manifold surfaces based on a binary voxel classification. However, in some - especially medical - applications, multi-labeled datasets, where up to eight differently labeled voxels can be adjacent, are subject to visualization resulting in non-manifold meshes. In addition to an efficient surface reconstruction method, a constrained geometric filter is developed which can be applied to these non-manifold meshes without producing ridges at mesh junctions.
