  • Onyango, Christine M.; Marchant, John A.; Zwiggelaar, Reyer (1997-06)
    No absolute certainty can be given for information derived from images. In most cases image analysis uses single algorithms, or multiple single algorithms' results which are combined in an ad hoc manner, to derive certain ...
  • Chen, Jingying; Tiddeman, Bernard Paul (Springer Berlin / Heidelberg, 2008-07-01)
    An efficient and robust facial feature detection and tracking system is presented in this paper. The system is capable of locating a human face automatically. Six facial feature points (pupils, nostrils and mouth corners) ...
  • 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 ...
  • Santos, Paulo E.; Fenelon, Valquiria; Dee, Hannah (2008)
  • Oliver, A.; Freixenet, Jordi; Marti, R.; Pont, J.; Perez, E.; Denton, Erika R. E.; Zwiggelaar, 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, Frederic (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 ...
  • 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 ...
  • 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 ...
  • Ashford, Isabella; Woodland, Alan (Nuffield Foundation, 2011-11-23)
  • Zwiggelaar, Reyer; Wilson, M. G. F. (1996)
    Experimental results are presented for the changes in the degree of polarization upon propagation in the LP(01) mode in a few-mode optical fibre. The dependence on the temporal coherence of the source is shown. The general ...
  • Fenelon, Valquiria; Dee, Hannah; Santos, Paulo E. (2009)
    Abstract Recently, cognitive psychologists and others have turned their attention to the formerly neglected study of shadows, and the information they purvey. These studies show that the human perceptual system values ...
  • Li, Longzhuang; Guardiola, Jose; Liu, Yonghuai (2011-11)
    Spatial features are important properties with respect to data integration in many areas such as ocean observational information and environmental decision making. In order to address the needs of these applications, we ...
  • Fenelon, Valquiria; Santos, Paulo E.; Dee, Hannah Mary; Cozman, Fabio G. (2013-06-01)
    This paper describes a logic-based formalism for qualitative spatial reasoning with cast shadows (Perceptual Qualitative Relations on Shadows, or PQRS) and presents results of a mobile robot qualitative self-localisation ...
  • Liu, Yonghuai (2009-06-01)
    Iterative algorithms are often used for range image matching. In this paper, we treat the iterative process of range image matching as a live biological system: evolving from one generation to another. Whilst different ...
  • Oliver, Arnau; Freixenet, Jordi; Marti, Joan; Denton, Erika R. E.; Zwiggelaar, Reyer; Pérez, Elsa; Pont, Josep (2010-02-01)
    The aim of this paper is to review existing approaches to the automatic detection and segmentation of masses in mammographic images, highlighting the key-points and main differences between the used strategies. The key ...
