    • Learnt Inverse Kinematics for Animation Synthesis 

      Ong, Eng-Jon; Hilton, Adrian (The Eurographics Association, 2005)
      Existing work on animation synthesis can be roughly split into two approaches, those that combine segments of motion capture data, and those that perform inverse kinematics. In this paper, we present a method for performing ...

    • Linear Hashtable Method and Predicted Hexagonal Search Algorithm with Moments Invariant 

      Wu, Yunsong; Megson, Graham; Nie, Zhengang; Liu, Xuan (The Eurographics Association, 2005)
      This paper presents a novel Linear Hashtable Method Predicted Hexagonal Search (LHMPHS) method for block base motion compensation on the basis of research from previous algorithm. Hashtable is used in video compression. ...

    • Merging Graphics and Vision for 3D Face Recognition 

      Bai, Li; Song, Yi (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 

      Madsen, Claus B.; Laursen, Rune (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 

      Moeslund, T. B.; Madsen, C. B.; Aagaard, M.; Lerche, D. (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 ...

    • Monte Carlo Noise Reduction Using Bayesian Method in Wavelet domain 

      Xu, Ruifeng; Pattanaik, Sumanta N. (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 

      Collomosse, J. P.; Hall, P. M. (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 

      Anantrasirichai, N.; Canagarajah, C. Nishan; Bull, David R. (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 

      Hillman, Peter M.; Hannah, John M. (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 

      Cerri, A.; Ferri, M.; Giorgi, D. (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 ...

    • On the Separation of Luminance from Colour in Images 

      Woodland, Alan; Labrosse, Frédéric (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 ...

    • Realistic Real-Time Hair Simulation and Rendering 

      Jung, Yvonne; Rettig, Alexander; Klar, Oliver; Lehr, Timo (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 ...

    • Regularised Anisotropic Nonlinear Diffusion for Rendering Refraction in Volume Graphics 

      Rodgman, David; Chen, Min (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 

      Collins, G.; Hilton, A. (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 

      Farenzena, Michela; Fusiello, Andrea (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 ...
