    • 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
