  • A method for clustering and cooperation in wireless multimedia sensor networks 

    Alaei, Mohammad; Barceló Ordinas, José María (2010-04)
    Article
    Accés obert
    Wireless multimedia sensor nodes sense areas that are uncorrelated to the areas covered by radio neighbouring sensors. Thus, node clustering for coordinating multimedia sensing and processing cannot be based on classical ...
  • 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
    Accés obert
    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 ...
  • Audiovisual event detection towards scene understanding 

    Canton Ferrer, Cristian; Butko, Taras; Segura, C.; Giró Nieto, Xavier; Nadeu Camprubí, Climent; Hernando Pericás, Francisco Javier; Casas Pla, Josep Ramon (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Acoustic events produced in meeting environments may contain useful information for perceptually aware interfaces and multimodal behavior analysis. In this paper, a system to detect and recognize these events from a ...
  • Combining geometric and appearance priors for robust homography estimation 

    Serradell, Eduard; Özuysa, Mustafa; Lepetit, Vincent; Fua, Pascal; Moreno-Noguer, Francesc (Springer, 2010)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Abstract. The homography between pairs of images are typically computed from the correspondence of keypoints, which are established by using image descriptors. When these descriptors are not reliable, either because of ...
  • Comparative analysis for detecting objects under cast shadows in video images 

    Scandaliaris, Jorge; Villamizar Vergel, Michael Alejandro; Sanfeliu Cortés, Alberto (2010)

  • Detección de objetos y anotación de imágenes en el iPhone 

    Blanco Almazan, M. Dolores (Universitat Politècnica de Catalunya, 2013-02-25)
    Projecte/Treball Final de Carrera
    Accés obert
    [ANGLÈS] This project is about object detection on a mobile device like iPhone. The iPhone tool allows users to take pictures, annotate them with bounding boxes and object tags and uploading the data to the server. With ...
  • Enhancing low-level features with mid-level cues 

    Trulls Fortuny, Eduard (Universitat Politècnica de Catalunya, 2015-02-20)
    Tesi
    Accés obert
    Local features have become an essential tool in visual recognition. Much of the progress in computer vision over the past decade has built on simple, local representations such as SIFT or HOG. SIFT in particular shifted ...
  • Measures and meta-measures for the supervised evaluation of image segmentation 

    Pont Tuset, Jordi; Marqués Acosta, Fernando (IEEE Computer Society Publications, 2013)
    Text en actes de congrés
    Accés obert
    This paper tackles the supervised evaluation of image segmentation algorithms. First, it surveys and structures the measures used to compare the segmentation results with a ground truth database, and proposes a new measure: ...
  • Object recognition in urban hyperspectral images using binary partition tree representation 

    Valero, Silvia; Salembier Clairon, Philippe Jean; Chanussot, Jocelyn (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In this work, an image representation based on Binary Partition Tree is proposed for object detection in hyperspectral images. The BPT representation defines a search space for constructing a robust object identification ...
  • Region-based face detection, segmentation and tracking. framework definition and application to other objects 

    Vilaplana Besler, Verónica (Universitat Politècnica de Catalunya, 2010-12-17)
    Tesi
    Accés obert
    One of the central problems in computer vision is the automatic recognition of object classes. In particular, the detection of the class of human faces is a problem that generates special interest due to the large number ...
