gSMOOTH: A Gradient Based Spatial and Temporal Method of Depth Image Enhancement

The depth images from RGB-D cameras contain a substantial amount of artifacts such as holes and flickering. Moreover, for fast moving objects in successive frames, we perceive ghosting artifacts on the depth images. Hence, the poor quality of the …

Robust Enhancement of Depth Images from Depth Sensors

In recent years, depth cameras (such as Microsoft Kinect and ToF cameras) have gained much popularity in computer graphics, visual computing and virtual reality communities due to their low price and easy availability. While depth cameras (e.g. …

Latency in Distributed Acquisition and Rendering for Telepresence Systems

Telepresence systems use 3D techniques to create a more natural human-centered communication over long distances. This work concentrates on the analysis of latency in telepresence systems where acquisition and rendering are distributed. Keeping …

Reducing Bandwidth Consumption in Parallel Networked Telepresence Environments

Systems for multi-camera telepresence utilizing Large High-Resolution Displays (LHRDs) face the problem of generating large amounts of dynamic data. These data have to be processed at the local capture site, aggregated from different nodes locally, …

A Geoscience Perspective on Immersive 3D Gridded Data Visualization

We describe visualization software, Visualizer, that was developed specifically for interactive, visual exploration in immersive virtual reality (VR) environments. Visualizer uses carefully optimized algorithms and data structures to support the high …

Velocity-Aligned Discrete Oriented Polytopes for Dynamic Collision Detection

We propose an acceleration scheme for many-body dynamic collision detection at interactive rates. We use the Velocity-Aligned Discrete Oriented Polytope (VADOP), a tight bounding volume representation that offers fast update rates and which is …

3D Warp Brush Modeling

We introduce 3D warp brush, a new method for interactive shape modeling in an immersive virtual reality environment. 3D warp brushes are implicitly defined tools that operate on triangle meshes. We combine the efficiency of explicit mesh …

Enabling Scientific Workflows in Virtual Reality

To advance research and improve the scientific return on data collection and interpretation efforts in the geosciences, we have developed methods of interactive visualization, with a special focus on immersive virtual reality (VR) environments. Earth …

Spatialized Audio Rendering for Immersive Virtual Environments

We present a spatialized audio rendering system for the use in immersive virtual environments. The system is optimized for rendering a sufficient number of dynamically moving sound sources in multi-speaker environments using off-the-shelf audio …

The Blue-C (Poster Session): Integrating Real Humans into a Networked Immersive Environment

In this paper, we report ongoing work in a new project, The Blue-C. The goal of this project is to build a collaborative, immersive virtual environment which will eventually integrate real humans, captured by a set of video cameras. Two Blue-C.s will …
