      Two proposals related to the evaluation of polygonal approximations are presented in this document. First, a new measurement, called normalized compression ratio and adjustment error (NCA), to provide a fair evaluation of ...

    • Comparing Evolutionary Algorithms and Particle Filters for Markerless Human Motion Capture 

      Yeguas-Bolívar, Enrique; Muñoz-Salinas, Rafael; Medina-Carnicer, R.; Carmona Poyato, Ángel (Elsevier, 2014)
      Markerless Human Motion Capture is the problem of determining the joints’ angles of a three-dimensional articulated body model that best matches current and past observations acquired by video cameras. The problem of ...

    • Entropy Volumes for Viewpoint Independent Gait Recognition 

      Medina-Carnicer, R.; Muñoz-Salinas, Rafael; López-Fernández, D.; Madrid-Cuevas, F.J.; Carmona Poyato, Ángel (2017-02-17)
      Gait as biometrics has been widely used for human identi cation. However, direction changes cause di culties for most of the gait recognition systems, due to appearance changes. This study presents an e cient multi-view ...

    • Keypoint descriptor fusion with Dempster-Shafer Theory 

      Mondéjar Guerra, Víctor Manuel; Muñoz-Salinas, Rafael; Marín-Jiménez, M.J.; Carmona Poyato, Ángel; Medina-Carnicer, R. (2017)
      Keypoint matching is the task of accurately nding the location of a scene point in two images. Many keypoint descriptors have been proposed in the literature aiming at providing robustness against scale, translation and ...

    • Librería para el procesamiento de señales digitales con computadora 

      Fernández García, Nicolás Luis; Carmona Poyato, Ángel; Medina-Carnicer, R. (Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2004)
