Variational Shape Approximation of Point Set Surfaces
Martin Skrodzki, Eric Zimmermann, Konrad Polthier
In this work, we present a translation of the complete pipeline for variational shape approximation (VSA) to the setting of point sets. First, we describe an explicit example for t…
A Consistent Discrete 3D Hodge-type Decomposition: implementation and practical evaluation
Faniry H. Razafindrazaka, Konstantin Poelke, Konrad Polthier +1
The Hodge decomposition provides a very powerful mathematical method for the analysis of 2D and 3D vector fields. It states roughly that any vector field can be -orthogonally…
Hodge Decomposition of the wall shear stress vector fields characterizing biological flows
Faniry H. Razafindrazaka, Pavlo Yevtushenko, Konstantin Poelke +2
A discrete boundary-sensitive Hodge decomposition is proposed as a central tool for the analysis of wall shear stress (WSS) vector fields in aortic blood flows. The method is based…
Robust and High Fidelity Mesh Denoising
Sunil Kumar Yadav, Ulrich Reitebuch, Konrad Polthier
This paper presents a simple and effective two-stage mesh denoising algorithm, where in the first stage, the face normal filtering is done by using the bilateral normal filtering i…
