    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 ...
  • Efficient cubic spline interpolation implemented with FIR filters 

    Ferrer Arnau, Luis Jorge; Reig Bolano, Ramon; Marti Puig, Pere; Manjabacas, A.; Parisi Baradad, Vicenç (2012-06-26)
    Article
    Open Access
    Classical Cubic spline interpolation needs to solve a set of equations of high dimension. In this work we show how to compute the interpolant using a FIR digital filter, with a reduced number of operations per interpolated ...
  • Efficient representation of contours using splines implemented with FIR filters 

    Ferrer Arnau, Luis Jorge; Parisi Baradad, Vicenç; Reig Bolano, Ramon; Marti Puig, Pere; Manjabacas, A. (2011)
    Conference report

    The interpolation of contour pixels, with splines, of an order greater than or equal to two, usually causes oscillations that do not fit the original shape. To overcome this we propose using a least squares filter before ...
  • Surface parameterization for smooth 3D shapes 

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

    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 ...
