    • Image data compression with FAPEC 

      Ahmadloo, Hamed (Universitat Politècnica de Catalunya, 2014-07-04)
      Master thesis
      Open Access
      Satellite data compression is very important for scientific missions, which often send large amounts of data during operations. Modern examples are Euclid, Solar Orbiter and the several Earth observation missions. However, ...

    • 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)
