Parameter Acquisition of Geometric Primitives within Virtual Environments for Internet-Based Telerobotics
(The Eurographics Association, 2003)With the aim of improving the efficiency of on-line modelling of virtual environments (VEs) in Internet-based telerobotics (IBT), this paper addresses the modelling of geometric primitives using only a single view of them. ... -
Prometheus: Facial Modelling, Tracking and Puppetry
(The Eurographics Association, 2003)The Prometheus project sought to create a real-time production chain for 3D content. This paper summarises the techniques that were developed for facial modelling, tracking and puppetry. The process used for creating ... -
Quasi-3D cell-based Animation
(The Eurographics Association, 2003)We present a method for image compositing and rendering using 2D geometric shapes or raster images as input primitives, disposed in a 3D environment around which the camera can move. An animation system has been implemented ... -
Real-Time Capture, Reconstruction and Insertion into Virtual World of Human Actors
(The Eurographics Association, 2003)In this paper, we show how to capture an actor with no intrusive trackers and without any special environment like blue set, how to estimate its 3D-geometry and how to insert this geometry into a virtual world in real-time. ... -
Real-Time Per-pixel Rendering of Bump-mapped Textures Captured using Photometric Stereo
(The Eurographics Association, 2003)We present recent results from an EPSRC funded project VirTex (Virtual Textile Catalogues). The goal of this project is to develop graphics and image-processing software for the capture, storage, search, retrieval and ... -
Realistic Real-Time Hair Simulation and Rendering
(The Eurographics Association, 2005)We present a method for realistic rendering and simulation of human hair in real-time, which is suitable for the use in complex virtual reality applications. Neighbouring hairs are combined into wisps and animated with our ... -
A Region Adjacency Tree Approach to the Detection and Design of Fiducials
(The Eurographics Association, 2003)We report a topological approach to fiducial recognition for real-time applications. Independence from geometry makes the system tolerant to severe distortion, and allows encoding of extra information. The method is based ... -
Regularised Anisotropic Nonlinear Diffusion for Rendering Refraction in Volume Graphics
(The Eurographics Association, 2005)Rendering refraction in volume graphics requires smoothly distributed normals to synthesise good quality visual representations. Such refractive visualisation is more susceptible to noise in the data than visualisations ... -
A Rigid Transform Basis for Animation Compression and Level of Detail
(The Eurographics Association, 2005)We present a scheme for achieving level of detail and compression for animation sequences with known constant connectivity. We suggest compression is useful to automatically create low levels of detail in animations which ... -
Rigorous Computing in Computer Vision
(The Eurographics Association, 2005)In this paper we discuss how Interval Analysis can be used to solve some problems in Computer Vision, namely autocalibration and triangulation. The crucial property of Interval Analysis is its ability to rigorously bound ... -
Semi-Automated Logging for Professional Media Applications
(The Eurographics Association, 2003)We report a novel method for logging and annotating video footage specifically for professional post-production and archivist end users. SALSA - Semi-Automated Logging with Semantic Annotation - is a hybrid system that ... -
Sensitivity Analysis in Image Synthesis
(The Eurographics Association, 2005)Intermediate virtual images are used in the evaluation of disparity estimations. The analysis is based on the effect of disparity inaccuracies in the relative quality of virtual images. The peak-signal-to-noise ratio and ... -
Studying the Fidelity Requirements for a Virtual Ballet Dancer
(The Eurographics Association, 2003)Teaching dance, especially ballet, usually involves the phrase: 'watch, copy and learn' and improvement is made by emulation. This involves not only how to achieve the steps but also the quality of the movement. In this ... -
SVD-Matching using SIFT Features
(The Eurographics Association, 2005)The paper tackles the problem of feature points matching between pair of images of the same scene. This is a key problem in computer vision. Among the many possible applications of feature matching we are motivated for ... -

Talking Faces - Technologies and Applications
(The Eurographics Association, 2005)Facial animation has been combined with text-to-speech synthesis to create innovative multimodal interfaces. In this lecture, we present the technology and architecture in order to use this multimodal interface in an ... -
Texture Mapping Volume Objects
(The Eurographics Association, 2005)We present a combination of image-based texture mapping and projective space (pseudo-solid) texture. This imagebased texture mapping is useful for objects defined from volume datasets. The paper makes three main contributions. ... -
Towards A 3D Virtual Studio for Human Appearance Capture
(The Eurographics Association, 2003)This paper introduces the concept of a ''3D Virtual Studio'' for human appearance capture, akin to the motion capture studio for human motion tracking. Ultimately the 3D Virtual Studio should enable video-realistic ... -
Use and Re-use of Facial Motion CaptureData
(The Eurographics Association, 2003)Motion capture (mocap) data is commonly used to recreate complex human motions in computer graphics. Markers are placed on an actor, and the captured movement of these markers allows us to animate computer-generated ...
