Variations on Image Reconstruction:Weighted Back Projection and Fourier Expectation Maximization
(The Eurographics Association, 2014)Expectation Maximization and Filtered Back Projection are two common techniques for Tomographic reconstruction of images and volumes. While papers often demonstrat that EM produces higher quality reconstructions, particularly ... -
Gap-Sensitive Segmentation and Restoration of Digital Images
(The Eurographics Association, 2014)Many methods exist for removing defects such as gaps, cracks, and disconnections from digital shapes. However, most such methods have several limitations, such as removing both erroneous and important shape details, or ... -
Interactive Projective Texturing for Non-Photorealistic Shading of Technical 3D Models
(The Eurographics Association, 2013)This paper presents a novel interactive rendering technique for creating and editing shadings for man-made objects in technical 3D visualizations. In contrast to shading approaches that use intensities computed based on ... -
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 ... -
Support for the Calculation of Stent Fatigue Fracture in Peripheral Arteries
(The Eurographics Association, 2013)Vascular stenting is a medical intervention in which a wire mesh tube is inserted into an artery or vein to provide internal support. This is a safe and common procedure, but stents are now increasingly being deployed in ... -
A Compact Tucker-Based Factorization Model for Heterogeneous Subsurface Scattering
(The Eurographics Association, 2013)This paper presents a novel compact factored subsurface scattering representation for optically thick, heterogeneous translucent materials. Our subsurface scattering representation is a combination of Tucker-based factorization ... -
Measuring Realism in Hair Rendering
(The Eurographics Association, 2013)Visualisation of hair is an extremely complex problem within the field of Computer Graphics. Over the last 10 years, huge strides have been made in the area of physically-based hair rendering, giving rise to many applications ... -
Acquisition, Representation and Rendering of Real-World Models using Polynomial Texture Maps in 3D
(The Eurographics Association, 2013)The ability to represent real-world objects digitally in a realistic manner is an indispensable tool for many applications. This paper proposes a method for acquiring, processing, representing, and rendering these digital ... -
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 ... -
A Fast Inverse Kinematics Solver using Intersection of Circles
(The Eurographics Association, 2013)Inverse Kinematics (IK) calculates the joint angles of an articulated object so that its end effector can be positioned as desired. This paper presents an efficient IK method using a geometric solver based on the intersection ... -
The Evaluation of Perceptual Effectiveness of Isosurface Rendering-based Uncertainty Visualization Techniques for Volumetric Scalar Data
(The Eurographics Association, 2013)Many techniques have been proposed to convey uncertainty in visualization. However, little research has been reported on the evaluation of their effectiveness.We present a user study that evaluates the perceptual effectiveness ... -
Geometry-based Algorithm for Detection of Asymmetric Tunnels in Protein Molecules
(The Eurographics Association, 2013)We present a novel geometry-based method for computing asymmetric tunnels and voids in proteins, approximating their real shape with selected precision. Our method combines ideas from Voronoi and grid based approaches for ... -
NetVis: a Visualization Tool Enabling Multiple Perspectives of Network Traffic Data
(The Eurographics Association, 2013)Computer network traffic visualizations deliver improved understanding of pattern-of-life for networks, and such enhanced awareness can facilitate the detection of malicious traffic. Existing tools often opt for graph or ... -
GPU Simulation of Finite Element Facial Soft-Tissue Models
(The Eurographics Association, 2013)Physically-based animation techniques enable more realistic and accurate animation to be created. We present a GPU-based finite element (FE) simulation and interactive visualisation system for efficiently producing ... -
Anatomically Plausible Surface Alignment and Reconstruction
