    • Analysis of Invariant Motion Components in Dynamic Video Content 

      Molina Leiva, Jose Antonio (Universitat Politècnica de Catalunya, 2011-07-12)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   École polytechnique fédérale de Lausanne
      English: The fast expansion of Internet and DVB channels has brought a fast increase of video footage which needs to be indexed for efficient and easy retrieval. A novel video structural dissimilarity metric based on ...
    • Approximation of face images by analytical model 

      Zhan, Yu (Universitat Politècnica de Catalunya / École polytechnique fédérale de Lausanne, 2012-02)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   École polytechnique fédérale de Lausanne
      English: in this thesis, we address the problem of learning a face manifold model from an input data, consisting of 2D face images such that the input images can be approximated well using the learned manifold. We compute ...
    • Bit Error Combating Network Coding Techniques 

      Guri Hundertmark, Pau Bernat (Universitat Politècnica de Catalunya, 2010-06)
      Master thesis (pre-Bologna period)
      Open Access
      The aim of this project is to propose a system that with less complexity than MIXIT could give better performance than Distributed Product Codes in media streaming over wireless networks.
    • Calibration of Images with 3D range scanner data 

      Adalid López, Víctor Javier (Universitat Politècnica de Catalunya, 2009-06)
      Master thesis (pre-Bologna period)
      Open Access
      3D laser range scanners are used in extraction of the 3D data in a scene. Main application areas are architecture, archeology and city planning. Thought the raw scanner data has a gray scale values, the 3D data can be ...
    • Dense disparity estimation for spherical images based on belief propagation 

      Cusco Mach, Josep (Universitat Politècnica de Catalunya, 2009-06)
      Master thesis
      Open Access
      A lot of applications in computer vision are based on a pixel-labelling problem, such as stereo matching, image restoration or object segmentation. In the last years great advances have been achieved in dense disparity ...
    • Multimedia Streaming over P2P networks using Markov Decision Processes 

      Gutiérrez Zulaica, Ester (Universitat Politècnica de Catalunya, 2010-05)
      Master thesis (pre-Bologna period)
      Open Access
      The aim of this project is to overcome the limitations of Foresighted Resource Reciprocation strategy (FRR) [11] for distributing multimedia content while providing a better performance for resource reciprocation than ...
    • P2P media delivery using scalable video coding 

      Carmona Tobella, Ismael Joan (Universitat Politècnica de Catalunya / École Polytechnique Fédérale de Lausanne, 2012-09-07)
      Master thesis
      Open Access
      [ANGLÈS] The consumptions of all forms of Internet video are constantly growing. For example, the collective sum of videos would be accounted for 86% of the global traffic by 2016. As the bandwidth requirement rises, the ...
    • Sensor network inference from partial and correlated observations 

      Contijoch Cullere, Xavier (Universitat Politècnica de Catalunya, 2011-07-12)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   École polytechnique fédérale de Lausanne
      English: Consider a Wireless Sensor Network (WSN) where links can fail and the structure is varying a lot in function of the application implemented. We design a routing and encoding algorithm robust to arbitrary wireless ...
