BTF-CIELab: A Perceptual Difference Measure for Quality Assessment and Compression of BTFs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Driven by the advances in lossy compression of bidirectional texture functions (BTFs), there is a growing need for reliable methods to numerically measure the visual quality of the various compressed representations. Based ...
Data Preparation for Real-time High Quality Rendering of Complex Models
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
The capability of current 3D acquisition systems to digitize the geometry reflection behaviour of objects as well as the sophisticated application of CAD techniques lead to rapidly growing digital models which pose new ...
Markerless Visual Human Movement Tracking for HCI: What Frequency?
(The Eurographics Association, 2009)
This paper tries to establish a minimal tracking frequency limit for visual human movement tracking algorithms that intend to be useful for the realization of some kind Human-Computer-Interaction (HCI) metaphor. More ...
River Networks for Instant Procedural Planets
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Realistic terrain models are required in many applications, especially in computer games. Commonly, procedural models are applied to generate the corresponding models and let users experience a wide variety of new environments. ...
Data-driven Local Coordinate Systems for Image-Based Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
Image-based representations of an object profit from known geometry. The more accurate this geometry is known, the better corresponding pixels in the different images can be aligned, which leads to less artifacts and better ...
GPU-based Collision Detection for Deformable Parameterized Surfaces
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
Based on the potential of current programmable GPUs, recently several approaches were developed that use the GPU to calculate deformations of surfaces like the folding of cloth or to convert higher level geometry to ...
Variational Surface Approximation and Model Selection
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We consider the problem of approximating an arbitrary generic surface with a given set of simple surface primitives. In contrast to previous approaches based on variational surface approximation, which are primarily concerned ...
Context Aware Terrain Visualization for Wayfinding and Navigation
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
To assist wayfinding and navigation, the display of maps and driving directions on mobile devices is nowadays commonplace. While existing system can naturally exploit GPS information to facilitate orientation, the inherently ...
Level-of-Detail Streaming and Rendering using Bidirectional Sparse Virtual Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Bidirectional Texture Functions (BTFs) are among the highest quality material representations available today and thus well suited whenever an exact reproduction of the appearance of a material or complete object is required. ...
Markerless 4 gestures 6 DOF real-time visual tracking of the human hand with automatic initialization
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this paper we present a novel computer vision based hand-tracking technique, which is capable of robustly tracking 6+4DOF of the human hand in real-time (at least 25 frames per second) with the help of 3 (or more) ...
