  • Labrosse, Frédéric (Unknown Publisher, 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 ...
  • Bunting, Peter John; Labrosse, Frédéric; Lucas, Richard Maxwell (2008-07-01)
    This paper outlines further tests of the automatic image-to-image registration technique of Bunting et al with the inclusion of joint histogram image similarity metrics. These metrics were expected to increase the accuracy ...
  • Ososinski, Marek; Labrosse, 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 ...
  • Murray, John C.; Neal, Mark James; Labrosse, Frédéric (2013-03)
    Aerial photographs and images are used by a variety of industries, including farming, landscaping, surveying, and agriculture, as well as academic researchers including archaeologists and geologists. Aerial imagery can ...
  • Havlena, M.; Jancošek, M.; Huber, B.; Labrosse, Frédéric; Tyler, Laurence Gethyn; Pajdla, T.; Paar, G.; Barnes, Dave (2011)
    We present an autonomous camera platform, the Aberystwyth University Aerobot, and an automatic re-construction pipeline generating triangulated 3D surface meshes and DEMs from the acquired images. The performance of the ...
  • McIntyre, James; Labrosse, Frédéric; Church, Andrew (2009-10-16)
    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 ...
  • Hosseini, H.; Neal, M. J.; Labrosse, Frédéric (School of Informatics, University of Edinburgh, 2008-09-01)
  • Cao, Juan; Labrosse, Frédéric; Dee, Hannah Mary (Springer, 2013-07-31)
    This paper describes a novel image-based method for robot orientation estimation based on a single omnidirectional camera. The estimation of orientation is computed by finding the best pixel-wise match between images as a ...
  • Clarke, Sebastian John; Labrosse, Frédéric; Trianni, Vito; Tuci, Elio (MIT Press, 2013-09-02)
    Autonomous robot road following has been widely investigated since the early 1980s and, whilst much progress has been shown, there is still no system which displays 100% generality across all types of problem. This work ...
  • Alotaibi, Najm; Labrosse, Frédéric (2013)
    We present a new image completion method that can deal with large holes surrounded by different types of structure and texture. Our approach is based upon creating image structure in the hole while preserving global image ...
  • Alotaibi, Najm (Aberystwyth UniversityComputer Science, 2009-08)
    In this thesis, we present a new image completion method that automates the filling in of holes left by the removal of undesired areas in images so that the final output image is visually plausible. The reconstruction ...
  • Williams, Richard David; Brasington, James; Vericat, Damia; Hicks, D. Murray; Labrosse, Frédéric; Neal, Mark (Elsevier, 2011-11-21)
    The availability of new geomatics technologies and methods has transformed the investigation of sediment transport rates using the morphological approach. Terrestrial laser scanning (TLS), in particular, has transformative ...
  • Bunting, Peter John; Labrosse, Frédéric; Lucas, Richard Maxwell (2010-08)
    To allow remotely sensed datasets to be used for data fusion, either to gain additional insight into the scene or for change detection, reliable spatial referencing is required. With modern remote sensing systems, reliable ...
  • Cao, Juan; Labrosse, Frédéric; Dee, Hannah Mary (Springer, 2012-07-10)
    In this work we tackle the issue of visually recognising a place without any prior knowledge of its position, even in a world where the same place can look different or many places can look identical. To achieve a fast and ...
  • Woodland, Alan (Aberystwyth UniversityComputer Science, 2010-03)
    Images of objects (e.g. a rotating teapot, views from a camera mounted on a robot, an actor illuminated from different positions on a hemisphere, etc.) which vary between them by some controlled parameter tend not to be ...
  • Woodland, Alan; Labrosse, Frédéric (2007-11-15)
    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 ...
  • Woodland, Alan; Labrosse, Frédéric; Ugail, Hassan (BMVA, 2009-09-28)
    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 ...
  • Paar, G.; Woods, Mark; Gimkiewicz, Christiane; Labrosse, Frédéric; Medina, Alberto; Tyler, Laurence Gethyn; Barnes, Dave; Fritz, Gerald; Kapellos, Konstantinos (2012)
    Mobile systems exploring Planetary surfaces in future will require more autonomy than today. The EU FP7-SPACE Project ProViScout (2010-2012) establishes the building blocks of such autonomous exploration systems in terms ...

  • Ososinski, Marek; Labrosse, Frédéric (Springer, 2012)
    Autonomous following of ill-defined roads is an important part of visual navigation systems. The majority of current image-based road following methods rely on computationally expensive algorithms. This paper presents an ...
