StegoNPR: Information Hiding in Painterly Renderings
(The Eurographics Association, 2013)
We present a novel steganographic technique for concealing information within an image. Uniquely we explore the practicality of hiding, and recovering, data within the pattern of brush strokes generated by a non-photorealistic ...
Multi-Perspective Detail+Overview Visualization for 3D Building Exploration
(The Eurographics Association, 2013)
Virtual 3D building models, as key elements of virtual 3D city models, are used in a growing number of application domains, such as geoanalysis, disaster management and architectural planning. Visualization systems for ...
Accurate and Marker-less Head Tracking Using Depth Sensors
(The Eurographics Association, 2013)
Parameterized, high-fidelity 3D surface models can not only be used for rendering animations in the context of Computer Graphics (CG), but have become increasingly popular for analyzing data, and thus making these accessible ...
A Cost Effective, Accurate Virtual Camera System for Games, Media Production and Interactive Visualisation Using Game Motion Controllers
(The Eurographics Association, 2013)
Virtual cameras and virtual production techniques are an indispensable tool in blockbuster filmmaking but due to their integration into commercial motion-capture solutions, they are currently out-of-reach to low-budget and ...
Resolution Estimation for Shadow Mapping
(The Eurographics Association, 2013)
We present an approach to efficiently reduce shadow map resolution while retaining high quality hard shadows. In the first step, we generate a list of sample points that are seen from the camera and then project these into ...
