    Venus Express is the first European mission to Venus and will help to answer questions such as: What governs the escape processes of the atmosphere? How did it end up with the atmospheric state it’s currently in? What ...
  • Naik, Nitin (Aberystwyth University, 2015)
    Designers of effective and efficient fuzzy systems have long recognised the value of inferential hybridity in the implementation of sparse fuzzy rule based systems. Which is to say: such systems should have recourse to ...
  • Frédéric; Martin; Mark (2010-08)
    The appearance-based approach towards robot navigation is based on a pixel-wise comparison of images. Recent research has shown that the Euclidean distance in image space provides a robust method for robot homing, navigation ...
  • James; Andrew; Frédéric (2009-09)
    In this paper, we present an efficient way of representing and tracking a moving object in images. In our approach, the object is visually represented as a set of pixels corresponding to an ideal view of the object as seen ...
  • Alan; Hassan; 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 ...
  • Frédéric (2006-10)
    In this article we present an algorithm to estimate the orientation of a robot relative to an orientation specified at the beginning of the process. This is done by computing the rotation of the robot between successive ...
  • Frédéric; James (2007-09)
    We present in this paper an application of previously developed techniques to the leader-follower formation problem, techniques that exclusively use vision. Contrary to other vision-based methods, the only information ...
  • Neal; Jonathan (2002-06)
    Recent work in Model Based Reasoning has resulted in the development of automated tools to perform Failure Mode Effects Analysis (FMEA) and Sneak Circuit Analysis (SCA). These tools work at the component level for individual ...
  • Stephen; Laurence; David Preston; Frédéric; Mark (2011-04)
    APIC (Automatic Pointing and Image Capture) is an automatic algorithm capable of identifying potential imaging targets in a single WAC (Wide Angled Camera) image and then reimaging these targets using a HRC (High Resolution ...
  • Alan; Frédéric (2008-06)
    Building computer representations of real objects, which could be archaeological artifacts or planned buildings, is a very active research area. Typically objects are represented in computer memory as a collection of ...
  • Frédéric (Prifysgol Aberystwyth, 2006-03-16)
    In this report we present an algorithm to estimate the heading of a robot relative to a heading specified at the beginning of the process. This is done by computing the rotation of the robot between successive panoramic ...
  • Alan; 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 ...
  • Frédéric (2007-09-30)
    In this paper, we present a method that uses panoramic images to perform long-range navigation as a succession of short-range homing steps along a route specified by appearances of the environment of the robot along the ...
  • Gunn, Matthew David (Aberystwyth UniversityComputer Science, 2014)
    Summary Mars has been the subject of much interest to science for many hundreds of years. For nearly four decades Landers have been sent to investigate the geology of the Martian surface and search for signs of life. Each ...
  • Marek; Frédéric (2013)
    Autonomous following of ill-defined roads is an important part of visual navigation systems. This paper presents an adaptive method that uses a statistical model of the color of the road surface within a trapezoidal shape ...
  • Liu, Junjie (Aberystwyth UniversityComputer Science, 2013)
    Abstract This PhD project is a collaboration between Smart Light Devices, Ltd. in Aberdeen and Aberystwyth University on the development of such 3D laser scanners with an ultimate aim to inspect the underwater oil and ...
  • Zhao, Yitian (Aberystwyth UniversityComputer Science, 2013)
    Abstract Unlike traditional 2D images, which are projections of the real world onto a two-dimensional surface, 3D images express the geometry of the objects of interest directly in terms of a set of points, a mesh, or a ...
  • MacParthaláin, Neil Seosamh; Shen, Qiang; Jensen, Richard (2006-09-04)
    Feature Selection (FS) methods based on fuzzy-rough set theory (FRFS) have employed the dependency function to guide the FS process with much success. More recently a method has been developed which uses fuzzy-entropy ...
  • MacParthaláin, Neil Seosamh; Jensen, Richard; Shen, Qiang (2008-06-01)
    Dataset dimensionality is undoubtedly the single most significant obstacle which exasperates any attempt to apply effective computational intelligence techniques to problem domains. In order to address this problem a ...
  • MacParthaláin, Neil Seosamh; Jensen, Richard; Shen, Qiang (2006-07-26)
    Feature Selection (FS) is a dimensionality reduction technique that aims to select a subset of the original features of a dataset which offer the most useful information. The benefits of feature selection include improved ...
