• openAccess   A General Qualitative Spatio-Temporal Model Based on Intervals 

      Martínez Martín, Ester; Escrig Monferrer, María Teresa; del Pobil, Angel P. J.UCS (2012)
      Many real-world problems involve qualitative reasoning about space and/or time. Actually, it is an adequate tool for dealing with situations in which information is not sufficiently precise. However, despite its numerous ...
    • closedAccess   A model for the qualitative description of images based on visual and spatial features 

      Falomir, Zoe; Museros, Lledó; Gonzalez Abril, Luis; Escrig Monferrer, María Teresa; Ortega, Juan Antonio Elsevier (2012-06)
      An approach that provides a qualitative description of any image is presented in this paper. The main visual features (shape and colour) and the main spatial features (fixed orientation, relative orientation and topology) ...
    • openAccess   A Qualitative Acceleration Model Based on Intervals 

      Martínez Martín, Ester; Escrig Monferrer, María Teresa; del Pobil, Angel P. Universidad de Salamanca (2013)
      On the way to autonomous service robots, spatial reasoning plays a main role since it properly deals with problems involving uncertainty. In particular, we are interested in knowing people's pose to avoid collisions. With ...
    • openAccess   Describing images using qualitative models and description logics 

      Falomir, Zoe; Jiménez Ruiz, Ernesto; Escrig Monferrer, María Teresa; Museros, Lledó Taylor & Francis (2011)
      Our approach describes any digital image qualitatively by detecting regions/objects inside it and describing their visual characteristics (shape and colour) and their spatial characteristics (orientation and topology) by ...
    • openAccess   Fuzzy distance sensor data integration and interpretation 

      Falomir, Zoe; Castelló, Vicente; Escrig Monferrer, María Teresa; Peris Broch, Juan Carlos World Scientific Publishing (2011-08)
      An approach to distance sensor data integration that obtains a robust interpretation of the robot environment is presented in this paper. This approach consists in obtaining patterns of fuzzy distance zones from sensor ...
