    In this paper we propose a new contour descriptor for reconstructing fish otolith contours that uses half the number of coefficients needed by the classical elliptical Fourier descriptors (EFDs) for the same accuracy. ...
  • Automated taxon identification of teleost fishes using an otolith online database-AFORO 

    Parisi Baradad, Vicenç; Manjabacas, A.; Lombarte, A.; Olivella, R.; Chic, Oscar; Piera, Jaume; Garcia Ladona, E. (2010-06)
    Article

    Automated Taxon Identification (ATI) systems that use a database to identify species or anatomical structures of species from different taxonomical groups have recently been developed. However, few of these works have ...
  • Density Local Discriminant Bases for the analysis of otolith morphology in fish identification applications 

    Soria Pérez, José Antonio; Parisi Baradad, Vicenç; Lombarte, A. (Centre de Publicacions del Campus Nord SCCL (CPET), 2010)

  • Feature selection for analyzing and retrieving fish otoliths using elliptic Fourier descriptors of shapes 

    Reig Bolano, Ramon; Marti Puig, Pere; Gallego, Esteve; Masferrer, Gerard; Lombarte, A.; Ferrer Arnau, Luis Jorge; Parisi Baradad, Vicenç (2011)
    Conference report

    This paper analyzes the characteristics of an experimental otolith retrieval system based on image contours described with Elliptical Fourier Descriptors (EFD). Otoliths are found in the inner ear of fish. Their shape ...

  • Surface parameterization for smooth 3D shapes

    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 ...
