Methods for the Virtual Unfolding of Thin-Layer Structures

Abstract:

Thin-layer structures are present in an abundance of objects. Their analysis is often hampered by the fact that they are usually occluded by other structures or the thin-layer structure itself. The latter is particularly true, if the thin-layer structure is not flat but strongly curved or even rolled or folded. The occlusion-free visualization and analysis of such structures require their extraction and, ideally, their flattening into the 2-dimensional (2D) plane. This process can be performed in three main steps: (1) generation of a geometric representation of the thin-layer structure with a 2D manifold surface; (2) flattening of this 2D manifold surface into the 2D plane with the aim to introduce as little distortions as possible; (3) volumetric transformation of the image data or direct visualization of the flattened thin-layer volume. Over the past years, we have substantially contributed to the field of virtual unfolding of thin-layer structures with innovative approaches. In this talk, I will present our approaches that address all three processing steps. The feasibility og the approaches will be supported by presenting results for several thin-layer structures such as rolled and folded ancient documents like papyrus as well as solver and lead sheets, but also batteries and even biological structures. The talk will be concluded by an analysis of some remaining challenges.
