Real-time Rendering of Stack-based Terrains
(The Eurographics Association, 2011)Usually, terrain rendering relies on a 2D regular grid of height values, the so called height field. Height fields describe 2.5D surfaces and are not able to present complex 3D terrain features. In contrast, a 3D data ... -
The Recognition of Ethnic Groups based on Histological Skin Properties
(The Eurographics Association, 2011)We present an algorithm to recognize ethnic groups based on biologically justified features, such as melanin or hemoglobin concentrations. These biophysical features are extracted from skin reflectance spectra and allow, ... -
RITK: The Range Imaging Toolkit - A Framework for 3-D Range Image Stream Processing
(The Eurographics Association, 2011)The recent introduction of low-cost devices for real-time acquisition of dense 3-D range imaging (RI) streams has attracted a great deal of attention. However, to date, there exists no open source framework that is explicitly ... -
SBL Mesh Filter: A Fast Separable Approximation of Bilateral Mesh Filtering
(The Eurographics Association, 2011)Bilateral mesh filtering is a simple and powerful feature-preserving filtering operator which allows to smooth or remove noise from surface meshes while preserving important features in a non-iterative way. However, to be ... -
Seamless Integration of Multimodal Shader Compositing into a Flexible Ray Casting Pipeline
(The Eurographics Association, 2011)In the last three years a number of multi-volume GPU ray casting systems have been presented. Some of them are very powerful and provide a wide variety of features. However, these approaches are either only capable of ... -
Simulating Deep Sea Underwater Images Using Physical Models for Light Attenuation, Scattering, and Refraction
(The Eurographics Association, 2011)When adapting computer vision algorithms to underwater imaging, two major differences in image formation occur. While still traveling through the water, light rays are scattered and absorbed depending on their wavelength, ... -
Smooth Transitions for Large Scale Changes in Multi-Resolution Images
(The Eurographics Association, 2011)Today's super zoom cameras offer a large optical zoom range of over 30x. It is easy to take a wide angle photograph of the scene together with a few zoomed in high resolution crops. Only little work has been done to ... -
Surface Flow from Visual Cues
(The Eurographics Association, 2011)In this paper we study the estimation of dense, instantaneous 3D motion fields over a non-rigidly moving surface observed by multi-camera systems. The motivation arises from multi-camera applications that require motion ... -
Surface Reconstruction from Multi-resolution Sample Points
(The Eurographics Association, 2011)Robust surface reconstruction from sample points is a challenging problem, especially for real-world input data. We significantly improve on a recent method by Hornung and Kobbelt [HK06b] by implementing three major ... -
A View-Dependent and Inter-Frame Coherent Visualization of Integral Lines using Screen Contribution
(The Eurographics Association, 2011)In vector field visualization, integral lines like stream, path, or streak lines are often used to examine the behavior of steady and unsteady flows. In 3D, however, visualizing integral lines is problematic since the ... -
Warp-based Near-Regular Texture Analysis for Image-based Texture Overlay
(The Eurographics Association, 2011)Image-based texture overlay or retexturing is the process of augmenting a surface in an image or a video sequence with a new, synthetic texture. Some properties of the original texture such as texture distortion as well ...
