VirtualDSA++: Automated Segmentation, Vessel Labeling, Occlusion Detection and Graph Search on CT-Angiography Data
(The Eurographics Association, 2020)
Computed Tomography Angiography (CTA) is one of the most commonly used modalities in the diagnosis of cerebrovascular diseases like ischemic strokes. Usually, the anatomy of interest in ischemic stroke cases is the Circle ...
High-Performance Image Filters via Sparse Approximations
(ACM, 2020)
We present a numerical optimization method to find highly efficient (sparse) approximations for convolutional image filters. Using a modified parallel tempering approach,we solve a constrained optimization that maximizes ...
Possibilities and Challenges of Portraying Cultural Heritage Artefacts using Augmented Reality: the Mjällby Crucifix Case Study
(The Eurographics Association, 2020)
The increasing application of immersive technologies, i.e. virtual reality (VR) and augmented reality (AR), in cultural heritage (CH) offers new ways of displaying artefacts and historical sites. VR and AR provide an added ...
Ernst Grube: A Contemporary Witness and His Memories Preserved with Volumetric Video
(The Eurographics Association, 2020)
''Ernst Grube - The Legacy'' is an immersive Virtual Reality documentary about the life of Ernst Grube, one of the last German Holocaust survivors. From interviews conducted inside a volumetric capture studio, dynamic ...
Concurrent Binary Trees (with application to longest edge bisection)
(ACM, 2020)
We introduce the concurrent binary tree (CBT), a novel concurrent representation to build and update arbitrary binary trees in parallel. Fundamentally, our representation consists of a binary heap, i.e., a 1D array, that ...
Effective Parallelization Strategies for Scalable, High-Performance Iterative Reconstruction
(The Eurographics Association, 2020)
Iterative reconstruction techniques in X-ray computed tomography converge to a result by successively refining increasingly accurate estimates. Compared to alternative approaches, iterative reconstruction imposes significant ...
High-Quality Rendering of Glyphs Using Hardware-Accelerated Ray Tracing
(The Eurographics Association, 2020)
Glyph rendering is an important scientific visualization technique for 3D, time-varying simulation data and for higherdimensional data in general. Though conceptually simple, there are several different challenges when ...
Fast Multi-View Rendering for Real-Time Applications
(The Eurographics Association, 2020)
Efficient rendering of multiple views can be a critical performance factor for real-time rendering applications. Generating more than one view multiplies the amount of rendered geometry, which can cause a huge performance ...
The Virtual Reality Flow Lens for Blood Flow Exploration
(The Eurographics Association, 2020)
The exploration of time-dependent measured or simulated blood flow is challenging due to the complex three-dimensional structure of vessels and blood flow patterns. Especially on a 2D screen, understanding their full shape ...
Learning Hand Anatomy with Sense of Embodiment
(The Eurographics Association, 2020)
We present a VR-based prototype for learning the hand anatomy. The prototype is designed to support embodied cognition, i.e., a learning process based on movements. The learner employs the prototype in VR by moving their ...
