Image Abstraction by Structure Adaptive Filtering
(The Eurographics Association, 2008)
In this work we present a framework of automatic non-photorealistic image processing techniques that create simplified stylistic illustrations from color images, videos and 3D renderings. To smooth low-contrast regions ...
Time-varying Image Data Visualization Framework for Application in Cardiac Catheterization Procedures
(The Eurographics Association, 2008)
Visualization plays an important role in image guided surgery. This paper presents a real-time 3D motion visualization method where pre-computed meshes of the beating heart are synchronized with and overlaid onto live X-ray ...
A Fast Algorithm for Painterly Rendering on Mobile Devices
(The Eurographics Association, 2008)
With the rapid growth of mobile graphics applications, non-photorealistic rendering algorithms developed particularly for devices with limited processor capabilities have become important in the areas of games design and ...
Game-Based Training in an Interactive Environment by means of OpenCrimeScene
(The Eurographics Association, 2008)
This paper presents a novel approach towards training with game elements in an interactive environment by means of OpenCrimeScene, a virtual 3D training system for crime scene investigation (CSI). The application is designed ...
A Haptic Rendering Algorithm for Drilling into Volume Data
(The Eurographics Association, 2008)
With the developments of volume visualisation technology for complex data sets comes new challenges in terms of user interaction and information extraction. Volume haptics has proven itself to be an effective way of ...
Efficient Path Matching Motion Generation Algorithm for Multi Agent Environment
(The Eurographics Association, 2008)
This paper presents an efficient method to generate a large amount of continuous motion data from motion captured data. Given user defined way point lists for each agent, the algorithm can automatically generate collision ...
A New Method for Interacting with Multi-Window Applications on Large, High Resolution Displays
(The Eurographics Association, 2008)
Physically large display walls can now be constructed using off-the-shelf computer hardware. The high resolution of these displays (e.g., 50 million pixels) means that a large quantity of data can be presented to users, ...
A Lemon is not a Monstar: Visualization of Singularities of Symmetric Second Rank Tensor Fields in the Plane
(The Eurographics Association, 2008)
In the visualization of the topology of second rank symmetric tensor fields in the plane one can extract some key points (degenerate points), and curves (separatrices) that characterize the qualitative behaviour of the ...
Generation and Tessellation of Tree Stems
(The Eurographics Association, 2008)
When visualizing tree stems and branches for use in interactive applications, the polygon models resolution are usually as low as possible to achieve a high frame rate. Also, to ease animation and mesh generation, each ...
Localised Topology Correction for Hypertextured Terrains
(The Eurographics Association, 2008)
Terrains for computer graphics have traditionally been modelled with height fields. In the case of procedurally defined terrains, the height field is generated by a displacement map z
