Merging Graphics and Vision for 3D Face Recognition
(The Eurographics Association, 2005)This paper presents a new approach to automatic 3D face modelling from unstructured point cloud data. An efficient B-Spline surface-fitting algorithm is used to obtain an initial parametric surface for each face point cloud ... -
A Model-Based Approach to Image Relighting with a Potential for Real-Time Implementation
(The Eurographics Association, 2005)Image relighting is a very unique special visual effect which promises to have many important practical applications. Image relighting is essentially the process of, given one or more images of some scene, computing what ... -
Modeling Falling and Accumulating Snow
(The Eurographics Association, 2005)The use of computer graphics to produce special effects is currently being applied with great results in especially the entertainment and game industry. One area where computer graphics is not quite ready to replace all ... -
Models from Image Triplets using Epipolar Gradient Features
(The Eurographics Association, 2003)In an application where sparse matching of feature points is used towards fast scene reconstruction, the choice of the type of features to be matched has an important impact on the quality of the resulting model. In this ... -
Monte Carlo Noise Reduction Using Bayesian Method in Wavelet domain
(The Eurographics Association, 2005)A novel post-processing approach for removing Monte Carlo noises in synthetic images is presented in this paper. This paper first presents our findings on the statistical characteristics of the Monte Carlo noise, and then ... -
Motion Analysis in Video: Dolls, Dynamic Cues and Modern Art
(The Eurographics Association, 2005)This paper addresses the problem of synthesising animations from video clips; in particular emphasising the motion of tracked objects. We introduce "dynamic cues" as a class of motion emphasis cue, encompassing traditional ... -
Multi-View Image Coding with Wavelet Lifting Scheme
(The Eurographics Association, 2005)In this paper, we present a novel multi-view image codec based on a wavelet lifting scheme. The proposed algorithm applies the disparity estimation and compensation with the lifting scheme. It is very efficient in terms ... -
Natural Image Matting
(The Eurographics Association, 2005)Matte pulling - generating greyscale images which indicate segmentation of images into elements with subpixel accuracy and where blur causes pixels to be a mixture of elements - has received attention in recent years. Many ... -
A New Framework for Trademark Retrieval Based on Size Functions
(The Eurographics Association, 2005)We propose a new, effective system for Content Based trademark retrieval, which involves Size Functions. Three different classes of shape descriptors are combined, for a total amount of 25 measuring functions. The evaluation ... -
A Novel Form of Pointing Device
(The Eurographics Association, 2003)This paper presents a novel approach for man machine interaction applying real time computer vision techniques. We use a handheld camera to control the mouse cursor on a computer display. The camera captures an image of ... -
On the Editing of Images: Selecting, Cutting and Filling-in
(The Eurographics Association, 2003)This paper is two-fold. On the one hand, we present a system using qualitative spatial reasoning to help a user choose parts of an image that form interesting objects. The system then allows the user to cut these parts as ... -
On the Separation of Luminance from Colour in Images
(The Eurographics Association, 2005)Many computer vision and graphics related techniques rely upon illumination invariance of images to derive meaning from images of an object under varying lighting conditions. This is all the appearance-based methods. In ... -
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 ...
