Dynamic spherical harmonics approach for shape classification of migrating cells

Medyukhina, Anna ; Blickensdorf, Marco ; Cseresnyés, Zoltán ; Ruef, Nora ; Stein, Jens V. ; Figge, Marc Thilo

In: Scientific Reports, 2020, vol. 10, no. 1, p. 6072

Cell migration involves dynamic changes in cell shape. Intricate patterns of cell shape can be analyzed and classified using advanced shape descriptors, including spherical harmonics (SPHARM). Though SPHARM have been used to analyze and classify migrating cells, such classification did not exploit SPHARM spectra in their dynamics. Here, we examine whether additional information from dynamic...

Adapting spherical-harmonics-based geometric morphometrics (SPHARM) for 3D images containing large cavity openings using ambient occlusion: a study with hermit crab claw shape variability

In: Zoomorphology, 2020, p. -

One of the advantages of mesh-based geometric morphometrics (GM) over landmark-based approaches, is that it affords the possibility of the precise examination of highly irregular shapes and complex topographic surfaces. In the case of spherical-harmonic-based GM, the main prerequisite is a completely closed mesh surface, which is often lacking, particularly when dealing with natural objects....
