    • A new approach for multi-view gait recognition on unconstrained paths 

      Madrid-Cuevas, F.J.; Carmona Poyato, Ángel; Muñoz-Salinas, Rafael; Medina-Carnicer, R.; López-Fernández, D. (2017)
      Direction changes cause di culties for most of the gait recognition systems, due to appearance changes. We propose a new approach for multi-view gait recognition, which focuses on recognizing people walking on unconstrained ...

    • A new approach for optimal offline time-series segmentation with error bound guarantee 

      Carmona Poyato, Ángel; Fernández García, Nicolás Luis; Madrid-Cuevas, F.J.; Durán Rosal, Antonio Manuel (Elsevier, 2021)
      This paper proposes a new optimal approach, called OSFS, based on feasible space (FS) Liu et al. (2008)[, that minimizes the number of segments of the approximation and guarantees the error bound using the L∞-norm. On the ...

    • A new approach for optimal time-series segmentation 

      Carmona Poyato, Ángel; Fernández García, Nicolás Luis; Madrid-Cuevas, F.J.; Durán Rosal, Antonio Manuel (Elsevier, 2020)
      This paper proposes a new optimal approach, called OSTS, to improve the segmentation of time series. The proposed method is based on A* algorithm and it uses an improved version of the well-known Salotti method for obtaining ...

    • A new thresholding approach for automatic generation of polygonal approximations 

      Fernández García, Nicolás Luis; Moral Martínez, Luis del; Carmona Poyato, Ángel; Medina-Carnicer, R.; Madrid-Cuevas, F.J. (Elsevier, 2016)
      The present paper proposes a new algorithm for automatic generation of polygonal approximations of 2D closed contours based on a new thresholding method. The new proposal computes the signi cance level of the contour points ...

    • Assessing polygonal approximations: A new measurement and a comparative study 

      Fernández García, Nicolás Luis; Moral Martínez, Luis del; Carmona Poyato, Ángel; Madrid-Cuevas, F.J.; Medina-Carnicer, R. (Elsevier, 2023)
      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 ...

    • 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 ...

    • Multi-view gait recognition on curved 

      López-Fernández, D.; Madrid-Cuevas, F.J.; Carmona Poyato, Ángel; Muñoz-Salinas, Rafael; Medina-Carnicer, R. (2017-12-11)
      Appearance changes due to viewing angle changes cause difficulties for most of the gait recognition methods. In this paper, we propose a new approach for multi-view recognition, which allows to recognize people walking on ...

    • Optimal online time-series segmentation 

      Carmona Poyato, Ángel; Fernández García, Nicolás Luis; Madrid-Cuevas, F.J.; Muñoz-Salinas, Rafael; Romero Ramírez, Francisco J. (Springer, 2024)
      When time series are processed, the difficulty increases with the size of the series. This fact is aggravated when time series are processed online, since their size increases indefinitely. Therefore, reducing their number ...

    • Sistema digital de catalogación y consulta de documentos académicos: Tesis, Tesinas, Proyectos de Fin de Carrera 

      Fernández García, Nicolás Luis; Malagón Oloya, Pablo José; Medina-Carnicer, R.; Madrid-Cuevas, F.J.; Carmona Poyato, Ángel (Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2005)
      A digital system has been developed on order to catalogue and consult academic documents: Theses, First Degree Dissertations and Technical Degree Final Projects. The system uses a listing of bibliographical subjects which ...

    • Stereo Pictorial Structure for 2D Articulated Human Pose Estimation 

      López-Quintero, Manuel I.; Marín-Jiménez, M.J.; Muñoz-Salinas, Rafael; Madrid-Cuevas, F.J.; Medina-Carnicer, R. (2015)
      In this paper, we consider the problem of 2D human pose estimation on stereo image pairs. In particular, we aim at estimating the location, orientation and scale of upper-body parts of people detected in stereo image ...

    • The AVA Multi-View Dataset for Gait Recognition 

      López-Fernández, D.; Madrid-Cuevas, F.J.; Marín-Jiménez, M.J.; Muñoz-Salinas, Rafael; Carmona Poyato, Ángel (2018)
      In this paper, we introduce a new multi-view dataset for gait recognition. The dataset was recorded in an indoor scenario, using six convergent cameras setup to produce multi-view videos, where each video depicts a ...

    • Unsupervised generation of polygonal approximations based on the convex hull 

      Fernández García, Nicolás Luis; Moral Martínez, Luis del; Carmona Poyato, Ángel; Madrid-Cuevas, F.J.; Medina-Carnicer, R. (Elsevier, 2020)
      The present paper proposes a new non-optimal but unsupervised algorithm, called ICT-RDP, for generation of polygonal approximations based on the convex hull. Firstly, the new algorithm takes into account the convex hull ...
