  • Hogg, David C.; Dee, Hannah (2006)
    This paper will describe new work that attempts to perform the modelling of human behaviour not at the level of visible patterns of motion, but at the level of intentions. By inferring intentions in terms of known goals, ...
  • Dee, Hannah Mary; Hogg, David C. (2009-02-01)
    We propose a new method that treats visible human behaviour at the level of navigational strategies. By inferring intentions in terms of known goals, it is possible to explain the behaviour of people moving around within ...

  • A.; Jordi; R.; J.; E.; Erika R. E.; Reyer (2008-01-07)
    It has been shown that the accuracy of mammographic abnormality detection methods is strongly dependent on the breast tissue characteristics, where a dense breast drastically reduces detection sensitivity. In addition, ...

  • Woodland, Alan; Labrosse, Frédéric (Eurographics, 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 ...
  • Zwiggelaar, Reyer; Bull, C. R. (1995)
    Links between the fractal Hausdorff dimension, the Fourier transform of two-dimensional scenes, and image segmentation by texture are discussed. It is shown that the fractal Hausdorff dimension can be derived by integration ...

  • Martí, R.; Martí, J.; Freixenet, J.; Zwiggelaar, Reyer; Vilanova, J.C.; Barceló, J. (2008-07)
    The paper presents and evaluates a speckle detection method for B-scan images. This is a fully automatic method and does not require information about the sensor parameters, which is often missing in retrospective studies. ...

  • Strange, Harry; Zwiggelaar, Reyer (2010)
    Manifold learning is a widely used statistical tool which reduces the dimensionality of a data set while aiming to maintain both local and global properties of the data. We present a novel manifold learning technique which ...

  • Woodland, Alan; Ugail, Hassan; Labrosse, Frédéric (British Machine Vision Association, 2007-09)
    This paper presents a method to extend PDE surfaces to high dimensional spaces. We review a common existing analytic solution, and show how it can be used straightforwardly to increase the dimension of the space the surface ...
  • Liu, Yonghuai (2011-05-01)
    For accurate registration of overlapping free form shapes, different points in one shape must select different points in another as their most sensible correspondents. To reach this ideal state, in this paper we develop a ...

  • Dee, Hannah; Santos, Paulo E. (2011-08-07)
    Recently, psychologists have turned their attention to the study of castshadows and demonstrated that the human perceptual system values information fromshadows very highly in the perception of spatial qualities, sometimes ...
