  • A contour based approach for bilateral mammogram registration using discrete wavelet analysis
    Reig Bolaño, Ramon; Parisi Baradad, Vicenç; Martí i Puig, Pere (Springer, 2009)
    Registration of mammograms is an essential step to increase the effectiveness of all screening programs planned to early detect breast cancer in asymptomatic women. New techniques based on data fusion of different spatial ...
  • A new otolith image contour descriptor based on partial reflection
    Reig Bolaño, Ramon; Martí i Puig, Pere; Lombarte, A.; Soria Pérez, José Antonio; Parisi Baradad, Vicenç (Springer, 2010)
    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. The ...
  • Radix-R FFT and IFFT factorizations for parallel implementation
    Martí i Puig, Pere; Reig Bolaño, Ramon; Parisi Baradad, Vicenç (Springer, 2009)
    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 ...
