Operators to calculate the derivative of digital signals
Ferrer Arnau, Luis Jorge; Mon González, Juan; Parisi Baradad, Vicenç (2013)
Comunicació de congrés
Accés obertThis 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'editorialThe 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'editorialIn 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'editorialTwo 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 obertThis 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'editorialIn 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 ...
