    • Lambertian Correction for Rough and Specular Surfaces 

      Robles-Kelly, A.; Hancock, E.R. (The Eurographics Association, 2003)
      This paper describes a method for performing Lambertian reflectance for rough and specular surfaces. Rather than using an existing reflectance model, we present a method for estimating the reflectance function from image ...
    • 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

    • 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 ...
    • Models from Image Triplets using Epipolar Gradient Features 

      Vincent, É.; Laganière, R. (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 

      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 ...
    • A Novel Form of Pointing Device 

      Cantzler, H.; Hoile, C. (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 

      Labrosse, F. (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 

      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 ...
