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

    Alaei, Mohammad; Barceló Ordinas, José María (2010-04)
    Article
    Open Access
    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 ...
  • 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)

    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)
    Conference report

    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)
    Conference report

  • Detección de objetos y anotación de imágenes en el iPhone 

    Blanco Almazan, M. Dolores (Universitat Politècnica de Catalunya, 2013-02-25)
    Master thesis (pre-Bologna period)
    Open Access
    [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 ...
  • Measures and meta-measures for the supervised evaluation of image segmentation 

    Pont Tuset, Jordi; Marqués Acosta, Fernando (IEEE Computer Society Publications, 2013)
    Conference report
    Open Access
    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)
    Conference report
    Restricted access - publisher's policy
    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 ...
