  • Ultrasound Image Dataset for Image Analysis Algorithms Evaluation 

    Cortes, Camilo; Kabongo, Luis; Macia, Ivan; Ruíz, Óscar E.; Florez, Julian (Springer Verlag, 2016)
    The use of ultrasound (US) imaging as an alternative for real-time computer assisted interventions is increasing -- Growing usage of US occurs despite of US lower imaging quality compared to other techniques and its ...
  • Extending Marching Cubes with Adaptative Methods to obtain more accurate iso-surfaces 

    Congote, John; Moreno, Aitor; Barandiaran, Iñigo; Barandiaran, Javier; Ruíz, Oscar (Springer Berlin Heidelberg, 2010)
    This work proposes an extension of the Marching Cubes algorithm, where the goal is to represent implicit functions with higher accuracy using the same grid size -- The proposed algorithm displaces the vertices of the cubes ...
  • Robust CT to US 3D-3D Registration by Using Principal Component Analysis and Kalman Filtering 

    Echeverría, Rebeca; Cortes, Camilo; Bertelsen, Alvaro; Macia, Ivan; Ruíz, Óscar E.; Flórez, Julián (2016-07)
    Algorithms based on the unscented Kalman filter (UKF) have been proposed as an alternative for registration of point clouds obtained from vertebral ultrasound (US) and computerised tomography (CT) scans, effectively handling ...
  • Volume Ray Casting in WebGL 

    Congote, John; Kabongo, Luis; Moreno, Aitor; Segura, Alvaro; Beristain, Andoni; Posada, Jorge; Ruíz, Oscar (Intech Open, 2012)
  • Evaluation of interest point detectors for image information extraction 

    Barandiaran, Iñigo; Goenetxea, Jon; Congote, John; Graña, Manuel; Ruíz, Oscar (2012)
    Interest points extraction and matching is a common task in many computer vision based application, which are used in different domains, such as 3D reconstruction, object recognition, or tracking -- We present an evaluation ...
  • Volume Visual Attention Maps (VVAM) in Ray-Casting Rendering 

    Beristain, Andoni; Congote, John; Ruíz, Óscar (IOS Press, 2012)
    This paper presents an extension visual attention maps for volume data visualization, where eye fixation points become rays in the 3D space, and the visual attention map becomes a volume -- This Volume Visual Attention Map ...
  • Statistical tuning of Adaptive-Weight Depth Map Algorithm 

    Hoyos, Alejandro; Congote, John; Barandiaran, Iñigo; Acosta, Diego; Ruíz, Óscar (Springer Berlin Heidelberg, 2011)
    In depth map generation, the settings of the algorithm parameters to yield an accurate disparity estimation are usually chosen empirically or based on unplanned experiments -- A systematic statistical approach including ...
