    • 3D objects reconstruction from frontal images: an example with guitars 

      Beacco Porres, Alejandro; Gallego Vila, Jaime; Slater, Mel (Springer, 2022-09-15)
      Article
      Open Access
      This work deals with the automatic 3D reconstruction of objects from frontal RGB images. This aims at a better understanding of the reconstruction of 3D objects from RGB images and their use in immersive virtual environments. ...
    • A separate reality : An update on place Illusion and plausibility in virtual reality 

      Slater, Mel; Banakou, Domna; Beacco Porres, Alejandro; Gallego Vila, Jaime; Macia Varela, Francisco; Oliva Martínez, Ramon (2022-06-27)
      Article
      Open Access
      We review the concept of presence in virtual reality, normally thought of as the sense of “being there” in the virtual world. We argued in a 2009 paper that presence consists of two orthogonal illusions that we refer to ...
    • Automatic 3D avatar generation from a single RBG frontal image 

      Beacco Porres, Alejandro; Gallego Vila, Jaime; Slater, Mel (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference lecture
      Open Access
      We present a complete automatic system to obtain a realistic 3D avatar reconstruction of a person using only a frontal RGB image. Our proposed workflow first determines the pose, shape and semantic information from the ...
    • Automatic 3D character reconstruction from frontal and lateral monocular 2D RGB views 

      Beacco Porres, Alejandro; Gallego Vila, Jaime; Slater, Mel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      We present an automatic animatable 3D character reconstruction method from frontal and lateral RGB pictures of the person to reconstruct. We propose a method where, after obtaining a 3D reconstruction from a frontal view, ...
    • Bayesian foreground segmentation and tracking using pixel-wise background model and region-based foreground model 

      Gallego Vila, Jaime; Pardàs Feliu, Montse; Haro, Gloria (IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
      Conference report
      Open Access
      In this paper we present a segmentation system for monocular video sequences with static camera that aims at foreground/ background separation and tracking. We propose to combine a simple pixel-wise model for the background ...
    • Disturbance and plausibility in a virtual rock concert: a pilot study 

      Beacco Porres, Alejandro; Oliva Martínez, Ramon; Cabreira Sánchez, Carlos; Gallego Vila, Jaime; Slater, Mel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      We present methods used to produce and study a first version of an attempt to reconstruct a 1983 live rock concert in virtual reality. An approximately 10 minute performance by the rock band Dire Straits was rendered in ...
    • Foreground objects segmentation for moving camera scenarios based on SCGMM 

      Gallego Vila, Jaime; Pardàs Feliu, Montse; Solano, Montse (2011)
      Conference report
      Restricted access - publisher's policy
      In this paper we present a new system for segmenting non-rigid objects in moving camera sequences for indoor and outdoor scenarios that achieves a correct object segmentation via global MAP-MRF framework formulation for ...

      In this paper we present a new system for segmenting non-rigid objects in moving camera sequences for indoor and outdoor sce narios that achieves a correct object segmentation via global MAP-MRF framework formulation for ...
    • Foreground segmentation and tracking based on foreground and background modeling techniques 

      Gallego Vila, Jaime (Universitat Politècnica de Catalunya, 2009-02-09)
      Master thesis
      Open Access
      The Project Framework is the detection and tracking of foreground objects in static and moving video sequences. The objective of a foreground segmentation and Tracking is to segment the scene in foreground objects and ...
    • Multiview foreground segmentation using 3D probabilistic model 

      Gallego Vila, Jaime; Pardàs Feliu, Montse (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference lecture
      Restricted access - publisher's policy
      We propose a complete multi-view foreground segmentation and 3D reconstruction system that defines a 3-dimensional probabilistic model to model the foreground object in the 3 spatial dimensions, thus gathering the information ...
    • Parametric region-based foreround segmentation in planar and multi-view sequences 

      Gallego Vila, Jaime (Universitat Politècnica de Catalunya, 2013-10-14)
      Doctoral thesis
      Open Access
      Foreground segmentation in video sequences is an important area of the image processing that attracts great interest among the scientist community, since it makes possible the detection of the objects that appear in the ...
