Real-time Deblocked GPU Rendering of Compressed Volumes
(The Eurographics Association, 2014)The wide majority of current state-of-the-art compressed GPU volume renderers are based on block-transform coding, which is susceptible to blocking artifacts, particularly at low bit-rates. In this paper we address the ... -
Efficient Self-Shadowing Using Image-Based Lighting on Glossy Surfaces
(The Eurographics Association, 2014)In this paper we present a novel natural illumination approach for real-time rasterization-based rendering with environment map-based high dynamic range lighting. Our approach allows to use all kinds of glossiness values ... -
Progressive Spectral Ray Differentials
(The Eurographics Association, 2014)Light travelling though refractive objects can lead to beautiful colourful illumination patterns resulting from dispersion on the object interfaces. While this can be accurately simulated by stochastic Monte-Carlo methods, ... -
Deep Screen Space for Indirect Lighting of Volumes
(The Eurographics Association, 2014)We present a method to render approximate indirect light transport from surfaces to volumes which is fully dynamic with respect to geometry, the medium and the main light sources, running at interactive speed. This is ... -
On the Suitability of Connectivity-Extended Local Embedding for Drawing Multivariate Graphs
(The Eurographics Association, 2014)Multivariate networks are present in various domains such as biology, or social science. In such networks, the nodes often have several quantitative attributes, which determine similarity of nodes (e.g., person's characteristics ... -
Exploring Simulation in Sensor Network Models
(The Eurographics Association, 2014)Simulation is an important measure to estimate different properties of a planned network such as throughput and cost. However, many parameters need to be adjusted to approximate real-world conditions properly. In this paper ... -
Hierarchical Brushing of High-Dimensional Data Sets Using Quality Metrics
(The Eurographics Association, 2014)In this paper, we present an interactive exploration framework that puts the human-in-the-loop with the application of quality metrics and brushing techniques for an efficient visual analysis of high-dimensional data sets. ... -
Online Adaptive PCA for Inverse Kinematics Hand Tracking
(The Eurographics Association, 2014)Recent approaches to real-time bare hand tracking estimate the hand's pose and posture by fitting a virtual hand model to RGBD sensor data using inverse kinematics. It has been shown that exploiting natural hand synergies ... -
SOAR: Stochastic Optimization for Affine global point set Registration
(The Eurographics Association, 2014)We introduce a stochastic algorithm for pairwise affine registration of partially overlapping 3D point clouds with unknown point correspondences. The algorithm recovers the globally optimal scale, rotation, and translation ... -
A Generalized 2D and 3D Multi-Sensor Data Integration Approach based on Signed Distance Functions for Multi-Modal Robotic Mapping
(The Eurographics Association, 2014)This paper describes a data integration approach for arbitrary 2D/3D depth sensing units exploiting assets of the signed distance function. The underlying framework generalizes the KinectFusion approach with an objectoriented ... -
High-Speed Object Tracking Using an Asynchronous Temporal Contrast Sensor
(The Eurographics Association, 2014)Purely image-based approaches to tracking objects in video sequences are more prone to failure the higher an object's speed, as it covers a greater distance over the camera's exposure time and is subject to increased motion ... -
Automated Detection of Anatomical Regions in Magnetic Resonance Images
(The Eurographics Association, 2014)Recognition of body parts in three-dimensional medical images is an important task in many clinical applications. It can facilitate image segmentation, registration methods and it can be the first step of an automatic ... -
Combined Three-Dimensional Visualization of Structural Connectivity and Cortex Parcellation
(The Eurographics Association, 2014)The human cortex is organized in spatially distinct regions of different functional units. Cortex parcellations based on magnetic resonance imaging (MRI) of living human subjects are common practice, and recently, structural ... -
Non-local Means for Scanning Transmission Electron Microscopy Images and Poisson Noise based on Adaptive Periodic Similarity Search and Patch Regularization
(The Eurographics Association, 2014)High-Angle Annular Darkfield Scanning Transmission Electron Microscopy (HAADF-STEM) allows to take images at atomic scale with a contrast proportional to the atomic number. STEM acquires an image line-by-line, pixel-by-pixel ... -
Real-time Canonical-angle Views in 3D Virtual Cities
(The Eurographics Association, 2014)Virtual city models are useful for navigation planning or the investigation of unknown regions. However, existing rendering systems often fail to provide optimal views during the exploration, introduce occlusions, or show ... -
Supporting Urban Search & Rescue Mission Planning through Visualization-Based Analysis
(The Eurographics Association, 2014)We propose a visualization system for incident commanders in urban search & rescue scenarios that supports access path planning for post-disaster structures. Utilizing point cloud data acquired from unmanned robots, ... -
Curvature-Based Crease Surfaces for Wave Visualization
(The Eurographics Association, 2014)The visualization and analysis of complex fields often requires identifying and extracting domain specific features. Through a collaboration with geophysicists we extend previous work on crease surfaces with a new and ... -
Comparative Evaluation of Feature Line Techniques for Shape Depiction
(The Eurographics Association, 2014)This paper presents a qualitative evaluation of feature line techniques on various surfaces. We introduce the most commonly used feature lines and compare them. The techniques were analyzed with respect to the degree of ... -
Pattern Search in Flows based on Similarity of Stream Line Segments
(The Eurographics Association, 2014)We propose a method that allows users to define flow features in form of patterns represented as sparse sets of stream line segments. Our approach finds ''similar'' occurrences in the same or other time steps. Related ... -
Towards Efficient Online Compression of Incrementally Acquired Point Clouds
(The Eurographics Association, 2014)We present a framework for the online compression of incrementally acquired point cloud data. For this, we extend an existing vector quantization-based offline point cloud compression algorithm to handle the challenges ...
