In this paper, we present a Delaunay refinement algorithm for 4-
dimensional (3D+t) segmented images. The output mesh is proved to consist
of sliver-free simplices. Assuming that the hyper-surface is a closed smooth
manifold, we also guarantee faithful geometric and topological approximation.
We implement and demonstrate the effectiveness of our method on
publicly available segmented cardiac images.
