UI-Net: Interactive Artificial Neural Networks for Iterative Image Segmentation Based on a User Model
(The Eurographics Association, 2017)
For complex segmentation tasks, fully automatic systems are inherently limited in their achievable accuracy for extracting relevant objects. Especially in cases where only few data sets need to be processed for a highly ...
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 ...
Reproduction of Gloss, Color and Relief of Paintings using 3D Scanning and 3D Printing
(The Eurographics Association, 2017)
High fidelity reproductions of paintings provide new opportunities to museums in preserving and providing access to cultural heritage. This paper presents an integrated system which is able to capture and fabricate color, ...
An Efficient Denoising Algorithm for Global Illumination
(ACM, 2017)
We propose a hybrid ray-tracing/rasterization strategy for real- time rendering enabled by a fast new denoising method. We factor global illumination into direct light at rasterized primary surfaces and two indirect lighting ...
Efficient Incoherent Ray Traversal on GPUs Through Compressed Wide BVHs
(ACM, 2017)
We present a GPU-based ray traversal algorithm that operates on compressed wide BVHs and maintains the traversal stack in a compressed format. Our method reduces the amount of memory traffic significantly, which translates ...
Timeline Scheduling for Out-of-Core Ray Batching
(ACM, 2017)
We present a timeline based scheduling method for Monte Carlo ray tracing of out-of-core models on distributed memory clusters. We abstract different setups of various compute and memory devices into a graph-based ...
MRI Hip Joint Segmentation: A Locally Bhattacharyya Weighted Hybrid 3D Level Set Approach
(The Eurographics Association, 2017)
In this paper, we propose a novel hybrid level set approach that locally balances the combined use of both Gradient Vector Flow and region based energy cost function by means of the Bhattacharyya coefficient. The local ...
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 ...
Pairwise Matching of Stone Tools Based on Flake-Surface Contour Points and Normals
(The Eurographics Association, 2017)
Stone tools constitute the main artifacts facilitating archaeological research of the Paleolithic era. The reassembly of stone tools is the most important research work for analyzing human activities of that period. In ...
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. ...
