  • 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
    Restricted access - publisher's policy
    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 ...
  • PolSAR time series processing with Binary Partition Trees 

    Alonso González, Alberto; López Martínez, Carlos; Salembier Clairon, Philippe Jean (Institute of Electrical and Electronics Engineers (IEEE), 2014-06-01)
    Article
    Restricted access - publisher's policy
    This paper deals with the processing of polarimetric synthetic aperture radar (SAR) time series. Different approaches to deal with the temporal dimension of the data are considered, which are derived from different target ...
  • Real-time fingertip localization conditioned on hand gesture classification 

    Suau, Xavier; Alcoverro Vidal, Marcel; López-Méndez, Adolfo; Ruiz Hidalgo, Javier; Casas Pla, Josep Ramon (2014-05-09)
    Article
    Restricted access - publisher's policy
    A method to obtain accurate hand gesture classification and fingertip localization from depth images is proposed. The Oriented Radial Distribution feature is utilized, exploiting its ability to globally describe hand poses, ...
  • Segmentation hyperspectrale de forets tropicales par arbres de partition binaires 

    Tochon, Guillaume; Feret, J.B.; Valero, Silvia; Martin, R.E.; Tupayachi, R.; Chanussot, Jocelyn; Salembier Clairon, Philippe Jean; Asner, G.P. (2013-05-01)
    Article

    La segmentation d’images de forêts tropicales est un outil important pour faciliter le travail des écologues. Dans ce papier, nous proposons une nouvelle méthode de segmentation pour les images hyperspectrales, basée sur ...
  • Depth order estimation for video frames using motion occlusions 

    Palou, Guillem; Salembier Clairon, Philippe Jean (2014-04-01)
    Article
    Restricted access - publisher's policy
    This study proposes a system to estimate the depth order of regions belonging to a monocular image sequence. For each frame, the regions are ordered according to their relative depth using information from the previous and ...
  • Region-based caption text extraction 

    León Cristóbal, Miriam; Vilaplana Besler, Verónica; Gasull Llampallas, Antoni; Marqués Acosta, Fernando (Springer, 2013)
    Article
    Open Access
    This chapter presents a method for caption text detection. The proposed method will be included in a generic indexing system dealing with other semantic concepts which are to be automatically detected as well. To have a ...
  • Region based foreground segmentation combining color and depth sensors via logarithmic opinion pool decision 

    Gallego Vila, Jaime; Pardàs Feliu, Montse (2013-04-01)
    Article
    Restricted access - publisher's policy
    In this paper we present a novel foreground segmentation system that combines color and depth sensors information to perform a more complete Bayesian segmentation between foreground and background classes. The system shows ...
