    • Dynamic Video Face Transformation Using Multilinear and Autoregressive Models 

      Tiddeman, Bernard; Hunter, David; Perrett, David (The Eurographics Association, 2011)
      In this paper we present a prototype system for altering perceived attributes of faces in video sequences, such as the apparent age, sex or emotional state. The system uses multilinear models to decompose the parameters ...

    • Visualisation of Blockplay in Early Childhood 

      Albin-Clark, Adrian; Howard, T. L. J.; Anderson, B. (The Eurographics Association, 2011)
      Observation of young children is common in educational settings. For trainee practitioners however, access to children is infrequent, and even then, only small amounts of observable activity can be captured. We have developed ...

    • Memory Efficient Surface Reconstruction Based on Self Organising Maps 

      Kaye, David Paul; Ivrissimtzis, Ioannis (The Eurographics Association, 2011)
      We propose a memory efficient, scalable surface reconstruction algorithm based on self organising maps (SOMs). Following previous approaches to SOM based implicit surface reconstruction, the proposed SOM has the geometry ...

    • Pixel-Level Algorithms for Drawing Curves 

      Liu, Yong Kui; Wang, Peng Jie; Zhao, Dan Dan; Spelic, Denis; Mongus, Domen; Zalik, Borut (The Eurographics Association, 2011)
      This paper introduces new pixel level algorithms for parametric curves. The optimal value of the steps is first derived when rastrerizing parametric curves. A double-step algorithm using only integer arithmetic is presented ...

    • Building a Video Wall for Earth Observation Data 

      Bennett, Victoria; Haffegee, Adrian; Matthews, Brian; Nagella, Srikanth; Shaw, Andrew; Styles, Jon (The Eurographics Association, 2011)
      Earth observation satellites are generating large amounts of data as they monitor the earth' environment. Large scale visualisation represents a powerful mechanism to explore and communicate this data; however, conventional ...

    • Morphological Analysis from Images of Hyphal Growth using a Fractional Dynamic Model 

      Blackledge, Jonathan M.; Barry, D. J. (The Eurographics Association, 2011)
      The development of methods capable of accurately characterising the morphology of filamentous microbes represents a significant challenge to biotechnologists. This is because the productivity of many industrial fermentation ...

    • Terrain Models for Mass Movement Erosion 

      Hudák, Matej; Durikovic, R. (The Eurographics Association, 2011)
      In this paper we present a particle-based method for large scale long time progressive simulation of terrain erosion containing wet granular particles. The wetting process and the propagation through granular material is ...

    • Remodelling of Botanical Trees for Real-Time Simulation 

      Reynolds, Daniel T.; Laycock, Stephen D.; Day, Andy M. (The Eurographics Association, 2011)
      This paper proposes a technique to use virtual trees created with an industry recognised modelling tool. Initially the skeletal structure is extracted and processed to generate a continuous mesh suitable for high quality, ...
