  • 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 ...
  • Features extraction based on the Discrete Hartley Transform for closed contour
    Martí i Puig, Pere; Reig Bolaño, Ramon; Danés Garolera, Jaume (IOS Press, 2015)
    In this paper the authors propose a new closed contour descriptor that could be seen as a Feature Extractor of closed contours based on the Discrete Hartley Transform (DHT), its main characteristic is that uses only half ...
  • Quantitatively scoring behavior from video-recorded, long-lasting fish trajectories
    Martí i Puig, Pere; Serra i Serra, Moisès; Campos-Candela, A.; Reig Bolaño, Ramon; Manjabacas, A.; Palmer, M. (Elsevier, 2018)
    Scoring animal behavior is increasingly needed for better understanding ecological processes. For example, behavior shapes harvesting likelihood, thus management of harvested resources should improve after accounting for ...
  • 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 ...
  • Stereo Video Surveillance Multi-agent System: New Solutions for Human Motion Analysis
    Martí i Puig, Pere; Rodríguez, Sara; De Paz, Juan F.; Reig Bolaño, Ramon; Rubio, Manuel P.; Bajo, Javier (Springer, 2012)
    This article presents a distributed agent-based system that can process the visual information obtained by stereoscopic cameras. The system is embedded within a global project whose objective is to develop an ...
