  • Visual summary of egocentric photostreams by representative keyframes 

    Bolaños, Marc; Mestre, Ricard; Talavera, Estefanía; Giró Nieto, Xavier; Radeva, Petia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference lecture
    Open Access
    Building a visual summary from an egocentric photostream captured by a lifelogging wearable camera is of high interest for different applications (e.g. memory reinforcement). In this paper, we propose a new summarization ...
  • Event video retrieval using global and local descriptors in visual domain 

    Roldan-Carlos, Jennifer; Lux, Mathias; Giró Nieto, Xavier; Muñoz Trallero, Pia; Anagnostopoulos, Nektarios (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference lecture
    Open Access
    With the advent of affordable multimedia smart phones, it has become common that people take videos when they are at events. The larger the event, the larger is the amount of videos taken there and also, the more videos ...
  • Multiview foreground segmentation using 3D probabilistic model 

    Gallego Vila, Jaime; Pardàs Feliu, Montse (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference lecture
    Restricted access - publisher's policy
    We propose a complete multi-view foreground segmentation and 3D reconstruction system that defines a 3-dimensional probabilistic model to model the foreground object in the 3 spatial dimensions, thus gathering the information ...
  • Robust 3D SFS reconstruction based on reliability maps 

    Gallego Vila, Jaime; Pardàs Feliu, Montse (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference lecture

    Aquest treball vol promoure la col·laboració i coordinació entre assignatures de processat d'imatge/vídeo amb l’objectiu de potenciar els resultats en l'aprenentatge. Les principals contribucions son a) la creació d’un ...
  • 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 ...
  • Multiscale combinatorial grouping 

    Arbelaez, Pablo Andres; Pont Tuset, Jordi; Barron, Jonathan; Marqués Acosta, Fernando; Malik, Jitendra (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Open Access
    We propose a unified approach for bottom-up hierarchical image segmentation and object candidate generation for recognition, called Multiscale Combinatorial Grouping (MCG). For this purpose, we first develop a fast normalized ...
  • Microscopic simulation with AIMSUN for the assessment of incident management strategies 

    Barceló Bugeda, Jaime; Ferrer, J; Casas Pla, Josep Ramon; Montero Mercadé, Lídia; Perarnau, Josep (2002)
    Conference report
    Open Access
    PRIME (Prediction of Congestion and Incidents in Real Time, for Intelligent Incident Management and Emergency Traffic Management) was a project of the 5ht Framework Program of the European Union which objectives were to ...
  • Multidimensional SAR data analysis based on binary partition trees and the covariance matrix geometry 

    Alonso González, Alberto; López Martínez, Carlos; Salembier Clairon, Philippe Jean; Valero Valbuena, Silvia; Chanussot, Jocelyn (2014)
    Conference report
    Restricted access - publisher's policy
    In this paper, we propose the use of the Binary Partition Tree (BPT) as a region-based and multi-scale image representation to process multidimensional SAR data, with special emphasis on polarimetric SAR data. We also ...
