  • Monocular depth ordering using T-Junctions and convexity occlusion cues 

    Palou Visa, Guillem; Salembier Clairon, Philippe Jean (2013)
    Article
    Restricted access - publisher's policy
    This paper proposes a system that relates objects in an image using occlusion cues and arranges them according to depth. The system does not rely on a priori knowledge of the scene structure and focuses on detecting ...
  • An improved maximum likelihood method for power spectral density estimation 

    Lagunas Hernandez, Miguel A.; Gasull Llampallas, Antoni (1984-02)
    Article
    Open Access
  • Assessment of crowdsourcing and gamification loss in user-assisted object segmentation 

    Carlier, Axel; Salvador Aguilera, Amaia; Cabezas, Ferran; Giró Nieto, Xavier; Charvillat, Vincent; Marques, Oge (2015-09-12)
    Article
    Restricted access - publisher's policy
    There has been a growing interest in applying human computation – particularly crowdsourcing techniques – to assist in the solution of multimedia, image processing, and computer vision problems which are still too difficult ...
  • NetBenchmark: a bioconductor package for reproducible benchmarks of gene regulatory network inference 

    Bellot Pujalte, Pau; Olsen, Catharina; Salembier Clairon, Philippe Jean; Oliveras Vergés, Albert; Meyer, Patrick E. (2015-09-29)
    Article
    Open Access
    Background: In the last decade, a great number of methods for reconstructing gene regulatory networks from expression data have been proposed. However, very few tools and datasets allow to evaluate accurately and reproducibly ...
  • On the use of binary partition trees for the tree crown segmentation of tropical rainforest hyperspectral images 

    Tochon, Guillaume; Feret, Jean-Baptiste; Valero Valbuena, Silvia; Martin, Roberta E.; Knapp, David E; Salembier Clairon, Philippe Jean; Chanussot, Jocelyn; Asner, Gregory P. (2015-03-05)
    Article

    The segmentation of remotely sensed images acquired over tropical forests is of great interest for numerous ecological applications, such as forest inventories or conservation and management of ecosystems, for which species ...
  • Improving object segmentation by using EEG signals and rapid serial visual presentation 

    Mohedano, Eva; Healy, Graham; McGuinness, Kevin; Giró Nieto, Xavier; O'Connor, Noel; Smeaton, Alan F. (2015-07-31)
    Article
    Restricted access - publisher's policy
    This paper extends our previous work on the potential of EEG-based brain computer interfaces to segment salient objects in images. The proposed system analyzes the Event Related Potentials (ERP) generated by the rapid ...
  • Fast super-resolution via dense local training and inverse regressor search 

    Pérez-Pellitero, Eduardo; Salvador, Jordi; Torres-Xirau, Iban; Ruiz Hidalgo, Javier; Rosenhahn, Bodo (2014-11-01)
    Article
    Open Access
    Regression-based Super-Resolution (SR) addresses the upscaling problem by learning a mapping function (i.e. regressor) from the low-resolution to the high-resolution manifold. Under the locally linear assumption, this ...
  • Object recognition in hyperspectral images using Binary Partition Tree representation 

    Valero Valbuena, Silvia; Salembier Clairon, Philippe Jean; Chanussot, Jocelyn (2015-04-15)
    Article
    Restricted access - publisher's policy
    In this work, an image representation based on Binary Partition Tree is proposed for object detection in hyperspectral images. This hierarchical region-based representation can be interpreted as a set of hierarchical regions ...
  • Detecting end-effectors on 2.5D data using geometric deformable models: application to human pose estimation 

    Suau Cuadros, Xavier; Ruiz Hidalgo, Javier; Casas Pla, Josep Ramon (2013-03)
    Article
    Restricted access - publisher's policy
    End-effectors are usually related to the location of limbs, and their reliable detection enables robust body tracking as well as accurate pose estimation. Recent innovation in depth cameras has re-stated the pose estimation ...
  • Bilateral distance based filtering for polarimetric SAR data 

    Alonso González, Alberto; López Martínez, Carlos; Salembier Clairon, Philippe Jean; Deng, Xinping (2013-10-30)
    Article
    Open Access
    This paper introduces a non-linear Polarimetric SAR data filtering approach able to preserve the edges and small details of the data. It is based on exploiting the data locality in both, the spatial and the polarimetric ...
