  • Measures and meta-measures for the supervised evaluation of image segmentation 

    Pont Tuset, Jordi; Marqués Acosta, Fernando (IEEE Computer Society Publications, 2013)
    Conference report
    Open Access
    This paper tackles the supervised evaluation of image segmentation algorithms. First, it surveys and structures the measures used to compare the segmentation results with a ground truth database, and proposes a new measure: ...
  • Parameter determination of ONN (Ordered Neural Networks) 

    Pont Tuset, Jordi; Medrano Gracia, Pau; Nin Guerrero, Jordi; Larriba Pey, Josep; Muntés Mulero, Víctor (2007)
    External research report
    Open Access
    The need for data privacy motivates the development of new methods that allow to protect data minimizing the disclosure risk without losing information. In this paper, we propose a new protection method for numerical data ...
  • System architecture of a web service for Content-Based Image Retrieval 

    Giró Nieto, Xavier; Ventura, Carles; Pont Tuset, Jordi; Cortés Yuste, Silvia; Marqués Acosta, Fernando (Association for Computing Machinery (ACM), 2010)
    Conference lecture
    Open Access
    This paper presents the system architecture of a Content- Based Image Retrieval system implemented as a web service. The proposed solution is composed of two parts, a client run- ning a graphical user interface for query ...
  • Upper-bound assessment of the spatial accuracy of hierarchical region-based image representations 

    Pont Tuset, Jordi; Marqués Acosta, Fernando (IEEE, 2012)
    Conference report
    Restricted access - publisher's policy
    Hierarchical region-based image representations are versatile tools for segmentation, filtering, object detection, etc. The evaluation of their spatial accuracy has been usually performed assessing the final result of an ...
