      Perez-Sala, Xavier; Angulo Bahón, Cecilio; Escalera, Sergio (2011-06)
      Article
      Restricted access - publisher's policy
      An exportable and robust system using only camera images is proposed for path execution in robot navigation. Motion information is extracted in the form of optical flow from SURF robust descriptors of consecutive frames, ...

    • BoVDW: Bag-of-Visual-and-Depth-Words for gesture recognition 

      Hernandez Vela, Antonio; Bautista, Miguel Angel; Perez-Sala, Xavier; Ponce, Víctor; Baró, Xavier; Pujol, Oriol; Angulo Bahón, Cecilio; Escalera, Sergio (2012)
      Conference report
      Restricted access - publisher's policy
      We present a Bag-of-Visual-and-Depth-Words (BoVDW) model for gesture recognition, an extension of the Bag-of-Visual-Words (BoVW) model, that benefits from the multimodal fusion of visual and depth features. State-of-the-art ...
    • Efficient complementary viewpoint selection in volume rendering 

      Grau Carrión, Sergi; Puig Puig, Anna; Escalera, Sergio; Salamó, Maria; Amoros, Oscar (2013)
      Conference report
      Open Access
      A major goal of visualization is to appropriately express knowledge of scientific data. Generally, gathering visual information contained in the volume data often requires a lot of expertise from the final user to setup ...
    • Intelligent interactive volume classification 

      Grau Carrión, Sergi; Puig Puig, Anna; Escalera, Sergio; Salamó, Maria (2013)
      Conference report
      Restricted access - publisher's policy
      This paper defines an intelligent and interactive framework to classify multiple regions of interest from the original data on demand, without requiring any preprocessing or previous segmentation. The proposed intelligent ...
    • Métodos automáticos para el análisis de la expresión oral y gestual en proyectos fin de carrera

      Conference lecture
      Open Access
      La comunicación y expresión oral es una competencia de especial relevancia en el EEES. No obstante, en muchas enseñanzas superiores la puesta en práctica de esta competencia ha sido relegada principalmente a la presentación ...
    • Probability-based Dynamic Time Warping and Bag-of-Visual-and-Depth-Words for Human Gesture Recognition in RGB-D 

      Hernández-Vela, Antonio; Bautista, Miguel Angel; Perez Sala, Xavier; Ponce, Víctor; Escalera, Sergio; Baró, Xavier; Pujol, Oriol; Angulo Bahón, Cecilio (2014-12)
      Article
      Restricted access - publisher's policy
      We present a methodology to address the problem of human gesture segmentation and recognition in video and depth image sequences. A Bag-of-Visual-and-Depth-Words (BoVDW) model is introduced as an extension of the ...
    • Subspace procrustes analysis 

      Perez Sala, Xavier; De La Torre, Fernando; Igual, Laura; Escalera, Sergio; Angulo Bahón, Cecilio (2014)
      Conference report
      Open Access
      Procrustes Analysis (PA) has been a popular technique to align and build 2-D statistical models of shapes. Given a set of 2-D shapes PA is applied to remove rigid transformations. Then, a non-rigid 2-D model is computed ...
