    • Aportacions de processament d'imatge per a sistemes de codificació 3D multivista i per a la detecció de text en contingut televisiu 

      Farré Guiu, Miquel Angel (Universitat Politècnica de Catalunya, 2011-07-04)
      Master thesis (pre-Bologna period)
      Open Access
      English: Firstly, in this report we will introduce a new method for 3D multiview video coding.This is based on the synthesis of views. This method allows the transmission of a number of views from the scene which is less ...

      Master thesis (pre-Bologna period)
      Open Access
      Estudio sobre la organización y el funcionamiento global de los sistemas de software y hardware de generación de gráficos 3D y la arquitectura hardware de la GPU ATILA, relatando los problemas relacionados con la calidad ...
    • Comparison of MPEG-7 descriptors for long term selection of reference frames 

      Ruiz Hidalgo, Javier; Salembier Clairon, Philippe Jean (2009)
      Conference lecture
      Open Access
      During the last years, the amount of multimedia content has greatly increased. This has multiplied the need of efficient compression of the content but also the ability to search, retrieve, browse, or filter it. Generally, ...
    • Compressive Sensing and Combinatorial algorithms for image compression 

      Arévalo López, Raúl (Universitat Politècnica de Catalunya, 2010-08)
      Master thesis (pre-Bologna period)
      Open Access
      The initial motivation of this Masters Thesis is the design and analysis of an image compression method based on Compressive Sensing. Compressigve Sensing is a technique which allows coding sparse signals by projecting ...
    • Estudio de viabilidad técnica e implementación de un sistema de transmisión de video adaptativo H264/SVC sobre TCP 

      Grau Gracia, Manel (Universitat Politècnica de Catalunya, 2014-06)
      Master thesis (pre-Bologna period)
      Open Access
      [ANGLÈS] H264/SVC video system development adaptive to network connections. In order to become adaptive, it has been done the necessary bandwidth monitoring in order to could transmit up to one of the possible extraction ...
    • Histogram based Hierarchical Data Representation for Microarray Classification 

      Kottath, Sandeep (Universitat Politècnica de Catalunya, 2012-09-03)
      Master thesis
      Open Access
      [ANGLÈS] A general framework for microarray classification relying on histogram based hierarchical clustering is proposed in this work. It produces precise and reliable classifiers based on a two-step approach. In the first ...
    • Joint FE-DNN modelling for TMS-induced EMG activations 

      Martínez Gost, Marc (Universitat Politècnica de Catalunya, 2019-06)
      Bachelor thesis
      Open Access
      Considering the vast amount of degrees of freedom that the Central Nervous System holds, synergies, understood as building blocks led by the linear combination of multiple muscles, a novel hypothesis to understand the ...
    • Locally-adaptive texture compression 

      Andújar Gran, Carlos Antonio; Martínez Bayona, Jonás (2009)
      Conference report
      Restricted access - publisher's policy
      Current schemes for texture compression fail to exploit spatial coherence in an adaptive manner due to the strict efficiency constraints imposed by GPU-based, fragment-level decompression. In this paper we present a texture ...
    • Modeling of contours in wavelet domain for generalized lifting image compression 

      Rolon Garrido, Julio Cesar; Ortega, Antonio; Salembier Clairon, Philippe Jean (2009)
      Conference report
      Open Access
      This paper introduces the design of context-based models of contours in the wavelet domain, which are used to construct generalized lifting (GL) mappings for image compression. The GL context-based mapping may significantly ...
    • 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 ...
