Localized Manifold Harmonics for Spectral Shape Analysis
(The Eurographics Association, 2017)
The use of Laplacian eigenfunctions is ubiquitous in a wide range of computer graphics and geometry processing applications. In particular, Laplacian eigenbases allow generalizing the classical Fourier analysis to manifolds. ...
A Primal-to-Primal Discretization of Exterior Calculus on Polygonal Meshes
(The Eurographics Association, 2017)
Discrete exterior calculus (DEC) offers a coordinate-free discretization of exterior calculus especially suited for computations on curved spaces. We present an extended version of DEC on surface meshes formed by general ...
PCR: A Geometric Cocktail for Triangulating Point Clouds Beautifully Without Angle Bounds
(The Eurographics Association, 2017)
Reconstructing a triangulated surface from a point cloud through a mesh growing algorithm is a difficult problem, in largely because they use bounds for the admissible dihedral angle to decide on the next triangle to be ...
Protein Shape Retrieval
(The Eurographics Association, 2017)
The large number of protein structures deposited in the protein database provide an opportunity to examine the structure relations using computational algorithms, which can be used to classify the structures based on shape ...
Photo-Guided Exploration of Volume Data Features
(The Eurographics Association, 2017)
In this work, we pose the question of whether, by considering qualitative information such as a sample target image as input, one can produce a rendered image of scientific data that is similar to the target. The algorithm ...
Interactive Exploration of Dissipation Element Geometry
(The Eurographics Association, 2017)
Dissipation elements (DE) define a geometrical structure for the analysis of small-scale turbulence. Existing analyses based on DEs focus on a statistical treatment of large populations of DEs. In this paper, we propose a ...
A Guided Spatial Transformer Network for Histology Cell Differentiation
(The Eurographics Association, 2017)
Identification and counting of cells and mitotic figures is a standard task in diagnostic histopathology. Due to the large overall cell count on histological slides and the potential sparse prevalence of some relevant cell ...
Visual Navigation Support for Liver Applicator Placement using Interactive Map Displays
(The Eurographics Association, 2017)
Navigated placement of an ablation applicator in liver surgery would benefit from an effective intraoperative visualization of delicate 3D anatomical structures. In this paper, we propose an approach that facilitates surgery ...
Application of Image Processing Functions for Brain Tumor Enhancement in Intraoperative Ultrasound Image Data
(The Eurographics Association, 2017)
Intraoperative ultrasound (iUS) imaging supports neurosurgeons significantly during brain tumor operations. At the beginning of the intervention the integration of the iUS image data within the navigation system guides the ...
CT-Based Navigation Guidance for Liver Tumor Ablation
(The Eurographics Association, 2017)
Image-guided thermal ablation procedures such as microwave ablation (MWA) or radiofrequency ablation (RFA) have become clinically accepted treatment options for liver tumors. The goal of these minimally invasive procedures ...
