  • 3D hierarchical optimization for multi-view depth map coding 

    Maceira, Marc; Varas, David; Morros Rubió, Josep Ramon; Ruiz Hidalgo, Javier; Marqués Acosta, Fernando (2017-11-28)
    Article
    Open Access
    Depth data has a widespread use since the popularity of high resolution 3D sensors. In multi-view sequences, depth information is used to supplement the color data of each view. This article proposes a joint encoding of ...
  • Face tracking using a region-based mean-shift algorithm with adaptive object and background models 

    Vilaplana Besler, Verónica; Varas, David (2009-05-29)
    Conference lecture
    Open Access
    This paper proposes a technique for face tracking based on the mean shift algorithm and the segmentation of the images into regions homogeneous in color. Object and background are explicitly modeled and updated through ...
  • Linking media: adopting semantic technologies for multimodal media connection 

    Fernàndez, Dèlia; Bou Balust, Elisenda; Giró Nieto, Xavier; Riviero, Juan Carlos; Espadaler, Joan; Rodríguez, David; Colom Serra, Aleix; Rimmerk, Joan Marco; Varas, David; Massuda, Issey; Roig, Carlos (CEUR-WS.org, 2018)
    Conference report
    Open Access
    Today's media and news organizations are constantly generating large amounts of multimedia content, majorly delivered online. As the online media market grows, the management and delivery of contents is becoming a challenge. ...
  • Multiresolution co-clustering for uncalibrated multiview segmentation 

    Ventura, Carles; Varas, David; Vilaplana Besler, Verónica; Giró Nieto, Xavier; Marqués Acosta, Fernando (2019-05-04)
    Article
    Restricted access - publisher's policy
    We propose a technique for coherently co-clustering uncalibrated views of a scene with a contour-based representation. Our work extends the previous framework, an iterative algorithm for segmenting sequences with small ...
  • ViTS: Video tagging system from massive web multimedia collections 

    Fernàndez, Dèlia; Varas, David; Espadaler, Joan; Masuda, Issey; Ferreira, Jordi; Woodward, Alejandro; Rodríguez, David; Giró Nieto, Xavier; Riveiro, Juan Carlos; Bou Balust, Elisenda (IEEE Press, 2017)
    Conference report
    Open Access
    The popularization of multimedia content on the Web has arised the need to automatically understand, index and retrieve it. In this paper we present ViTS, an automatic Video Tagging System which learns from videos, their ...
  • What is going on in the world? A display platform for media understanding 

    Fernàndez, Dèlia; Varas, David; Espadaler, Joan; Masuda, Issey; Giró Nieto, Xavier; Riveiro, Juan Carlos; Bou Balust, Elisenda (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
