    • Operators to calculate the derivative of digital signals 

      Ferrer Arnau, Luis Jorge; Mon González, Juan; Parisi Baradad, Vicenç (2013)
      Comunicació de congrés
      Accés obert
      This paper presents an FIR operator with a very low computational cost for calculating the first derivative of discrete band-limited signals. The basic idea is to use cubic spline polynomials for interpolating among the ...
    • Otolith shape classification for fish stock discrimination 

      Soria Pérez, José Antonio; Nasreddine, Kamal; Parisi Baradad, Vicenç; Ferrer Arnau, Luis Jorge; Benzinou, Abdesslam (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The shape analysis of otoliths, which are calcified structures in the inner ear of teleostean fishes, is known to be particularly relevant to address species identification and stock discrimination. Generally, scientists ...
    • Otoliths identifiers using image contours EFD 

      Reig Bolano, Ramon; Marti Puig, Pere; Rodríguez González, Sara; Bajo Pérez, Javier; Parisi Baradad, Vicenç; Lombarte, A. (Springer Berlín / Heidelberg, 2010-09)
      Article
      Accés restringit per política de l'editorial
      In this paper we analyze the characteristics of an experimental otolith identification system based on image contours described with Elliptical Fourier Descriptors (EFD). Otoliths are found in the inner ear of fishes. ...
    • Radix-R FFT and IFFT factorizations for parallel implementation 

      Marti Puig, Pere; Reig Bolano, Ramon; Parisi Baradad, Vicenç (2009)
      Article
      Accés restringit per política de l'editorial
      Two radix-R regular interconnection pattern families of factorizations for both the FFT and the IFFT -also known as parallel or Pease factorizations- are reformulated and presented. Number R is any power of 2 and N, the ...
    • Satellite image georegistration from coast-line codification 

      Reig Bolaño, Ramon; Parisi Baradad, Vicenç; García-Ladona, Emilio; Martí Puig, Pere (SARTI (Technological Development Centre of Remote Acquisition and Data processing Systems), 2008-04-08T14:22:11Z)
      Article
      Accés obert
      This paper presents a contour-based approach for automatic image registration in satellite oceanography. Accurate image georegistration is an essential step to increase the eff ectiveness of all the image processing ...
    • Surface parameterization for smooth 3D shapes 

      Marti Puig, Pere; Reig Bolano, Ramon; Manjabacas, A.; Ferrer Arnau, Luis Jorge; Parisi Baradad, Vicenç; Lombarte, A. (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this work we present a new method for compacting data from 3D shapes by extracting a 3D characteristic curve that we call a 3D signature. The 3D signature obtained preserves almost all the morphological shape ...
