  • A simple method of multiple camera calibration for the joint top view projection 

    Mozerov, Mikhail; Amato, Ariel; Al, Murad; Gonzàlez, Jordi (Springer, 2007)
    Part of book or chapter of book
    Open Access
    A simple method for multiple camera calibration based on a novel geometric derivation is presented. The main advantage of this method is that it uses only three points in the world coordinate system to achieve the calibration. ...
  • Computationally efficient graph matching via energy vector extraction 

    Amato, Ariel; Al, Murad; Lladós, Josep; Gonzàlez, Jordi (Springer, 2007)
    Conference report
    Open Access
    This paper presents a method for graph matching based on domain knowledge by quantifying representative graph features. Our method searches and extracts the most relevant cues in different graphs. Once these cues are ...
  • Constructing a path database for scene categorization 

    Baiget, Pau; Fernández, Carles; Amato, Ariel; Roca, Francesc Xavier; Gonzàlez, Jordi (s. n., 2007)
    Conference report
    Open Access
    Human behavior understanding in image sequences requires to study human interaction with the environment, because human beings behave depending on their location. Therefore, a semantic labeling of the scenario must be ...
  • Exploiting multiple cues in motion segmentation based on background subtraction 

    Huerta Casado, Iván; Amato, Ariel; Roca Marva, Francesc Xavier; González, Jordi (2013)
    Article
    Open Access
    This paper presents a novel algorithm for mobile-object segmentation from static background scenes, which is both robust and accurate under most of the common problems found in motion segmentation. In our first contribution, ...
  • Face detection in color images using primitive shape features 

    Al, Murad; Amato, Ariel; Roca, Francesc Xavier; Gonzàlez, Jordi (Springer, 2007)
    Part of book or chapter of book
    Open Access
    Face detection is a primary step in many applications such as face recognition, video surveillance, human computer interface, and expression recognition. Many existing detection techniques suffer under scale variation, ...
  • Finding faces in color images through primitive shape features 

    Al, Murad; Orozco, Francisco J.; Amato, Ariel; Roca, Francesc Xavier; Gonzàlez, Jordi (s. n., 2007)
    Conference report
    Open Access
    Face detection is a primary step in many applications such as face recognition, video surveillance, human computer interface, and expression recognition. Many existing detection techniques suffer under scale variation, ...
  • Moving cast shadows detection methods for video surveillance applications 

    Amato, Ariel; Huerta Casado, Iván; Mozerov, Mikhail; Roca Marva, Francesc Xavier; González Sabaté, Jordi (Springer, 2013)
    Part of book or chapter of book
    Restricted access - publisher's policy
    Moving cast shadows are a major concern in today’s performance from broad range of many vision-based surveillance applications because they highly difficult the object classification task. Several shadow detection methods ...
  • On-line one stroke character recognition using directional features 

    Al, Murad; Amato, Ariel; Sánchez, Gemma; Gonzàlez, Jordi (Springer, 2007)
    Conference report
    Open Access
    This paper presents a method based on directional features for recognizing on-line characters represented by one-stroke. A new alphabet is proposed, and each character is represented as a vector of directional angles. This ...
  • Trajectory fusion for multiple camera tracking 

    Amato, Ariel; Al, Murad; Mozerov, Mikhail; Gonzàlez, Jordi (Springer, 2007)
    Part of book or chapter of book
    Open Access
    In this paper we present a robust and efficient method to overcome the negative effects of occlusion in the tracking process of multiple agents. The proposed approach is based on the matching of multiple trajectories from ...
  • Trajectory occlusion handling with multiple view distance minimization clustering 

    Mozerov, Mikhail; Amato, Ariel; Roca Marva, Francesc Xavier; González Sabaté, Jordi (2008)
    Article
    Open Access
    A robust and efficient method for overcoming the negative effects of long-time occlusion in the tracking process is presented. The proposed approach is based on the matching of multiple trajectories in time. Trajectories ...
