Video Relighting Using Infrared Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Inappropriate lighting is often responsible for poor quality video. In most offices and homes, lighting is not designed for video conferencing. This can result in unevenly lit faces, distracting shadows, and unnatural ... -
View and Time Interpolation in Image Space
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The ability to interpolate between images taken at different time and viewpoints directly in image space opens up new possiblities. The goal of our work is to create plausible in-between images in real time without the ... -
Viewfinder Alignment
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The viewfinder of a digital camera has traditionally been used for one purpose: to display to the user a preview of what is seen through the camera s lens. High quality cameras are now available on devices such as mobile ... -
Virtual Klingler Dissection: Putting Fibers into Context
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Fiber tracking is a standard tool to estimate the course of major white matter tracts from diffusion tensor magnetic resonance imaging (DT-MRI) data. In this work, we aim at supporting the visual analysis of classical ... -
Visual Abstractions of Solvent Pathlines near Protein Cavities
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Water is known to play a crucial role in protein structure, flexibility and activity. The use of molecular dynamics simulations allows detailed studies of complex protein-solvent interactions. Cluster analysis and density-based ... -
Visual Analysis and Semantic Exploration of Urban LIDAR Change Detection
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Many previous approaches to detecting urban change from LIDAR point clouds interpolate the points into rasters, perform pixel-based image processing to detect changes, and produce 2D images as output. We present a method ... -
Visual Clustering in Parallel Coordinates
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Parallel coordinates have been widely applied to visualize high-dimensional and multivariate data, discerning patterns within the data through visual clustering. However, the effectiveness of this technique on large data ... -
Visual Comparison of Hierarchically Organized Data
(The Eurographics Association and Blackwell Publishing Ltd., 2008)We provide a novel visualization method for the comparison of hierarchically organized data. Our technique visualizes a pair of hierarchies that are to be compared and simultaneously depicts how these hierarchies are related ... -
The Visual Computing of Projector-Camera Systems
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This article focuses on real-time image correction techniques that enable projector-camera systems to display images onto screens that are not optimized for projections, such as geometrically complex, coloured and textured ... -
Visual Inspection of Multivariate Graphs
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Most graph visualization techniques focus on the structure of graphs and do not offer support for dealing with node attributes and edge labels. To enable users to detect relations and patterns in terms of data associated ... -
Visualizing Genome Expression and Regulatory Network Dynamics in Genomic and Metabolic Context
(The Eurographics Association and Blackwell Publishing Ltd., 2008)DNA microarrays are used to measure the expression levels of thousands of genes simultaneously. In a time series experiment, the gene expressions are measured as a function of time. We present an application for integrated ... -
Visualizing Underwater Ocean Optics
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Simulating the in-water ocean light field is a daunting task. Ocean waters are one of the richest participating media, where light interacts not only with water molecules, but with suspended particles and organic matter ... -
Volume and Isosurface Rendering with GPU-Accelerated Cell Projection*
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present an efficient Graphics Processing Unit GPU-based implementation of the Projected Tetrahedra (PT) algorithm. By reducing most of the CPU-GPU data transfer, the algorithm achieves interactive frame rates (up to 2.0 ... -
Zippy: A Framework for Computation and Visualization on a GPU Cluster
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Due to its high performance/cost ratio, a GPU cluster is an attractive platform for large scale general-purpose computation and visualization applications. However, the programming model for high performance general-purpose ... -
Untitled
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a planarity constraint and a novel three-dimensional (3D) point reconstruction algorithm for a multiview laser range slit scanner. The constraint is based on the fact that all observed points on a projected laser ...
