  • Resource-based modality selection in robot-assisted cognitive training 

    Taranovic, Aleksandar; Jevtic, Aleksandar; Hernández Farigola, Joan; Tantinyà, Natalia; Abdelnour, Carla; Torras, Carme (2018)
    Conference report
    Open Access
    The majority of socially assistive robots interact with their users using multiple modalities. Multimodality is an important feature that can enable them to adapt to the user behavior and the environment. In this work, we ...
  • Visual semantic re-ranker for text spotting 

    Sabir, Ahmed; Moreno-Noguer, Francesc; Padró, Lluís (2018)
    Conference report
    Open Access
    Many current state-of-the-art methods for text recognition are based on purely local information and ignore the semantic corre- lation between text and its surrounding visual context. In this paper, we propose a post-processing ...
  • Towards safety in physically assistive robots: eating assistance 

    Vila Abad, Maria; Canal Camprodon, Gerard; Alenyà Ribas, Guillem (2018)
    Conference report
    Open Access
    Safety is one of the base elements to build trust in robots. This paper studies remedies to unavoidable collisions using robotics assistive feeding as an example task. Firstly, we propose an attention mechanism so the user ...
  • Vehicle pose estimation using G-Net: multi-class localization and depth estimation 

    García López, Javier; Agudo Martínez, Antonio; Moreno-Noguer, Francesc (IOS Press, 2018)
    Conference report
    Open Access
    In this paper we present a new network architecture, called G-Net, for 3D pose estimation on RGB images which is trained in a weakly supervised manner. We introduce a two step pipeline based on region-based Convolutional ...
  • Geometry-aware network for non-rigid shape prediction from a single view 

    Pumarola Peris, Albert; Agudo Martínez, Antonio; Porzi, Lorenzo; Sanfeliu Cortés, Alberto; Lepetit, Vincent; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    We propose a method for predicting the 3D shape of a deformable surface from a single view. By contrast with previous approaches, we do not need a pre-registered template of the surface, and our method is robust to the ...
  • Unsupervised person image synthesis in arbitrary poses 

    Pumarola Peris, Albert; Agudo Martínez, Antonio; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    We present a novel approach for synthesizing photo-realistic images of people in arbitrary poses using generative adversarial learning. Given an input image of a person and a desired pose represented by a 2D skeleton, our ...
  • Hallucinating dense optical flow from sparse lidar for autonomous vehicles 

    Vaquero Gómez, Víctor; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    In this paper we propose a novel approach to estimate dense optical flow from sparse lidar data acquired on an autonomous vehicle. This is intended to be used as a drop-in replacement of any image-based optical flow system ...
  • 2D-to-3D facial expression transfer 

    Rotger Moll, Gemma; Lumbreras, Felipe; Moreno-Noguer, Francesc; Agudo Martínez, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    Automatically changing the expression and physical features of a face from an input image is a topic that has been traditionally tackled in a 2D domain. In this paper, we bring this problem to 3D and propose a framework ...
  • Image collection pop-up: 3D reconstruction and clustering of rigid and non-rigid categories 

    Agudo Martínez, Antonio; Pijoan Comas, Melcior; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    This paper introduces an approach to simultaneously estimate 3D shape, camera pose, and object and type of deformation clustering, from partial 2D annotations in a multi-instance collection of images. Furthermore, we can ...
  • Adaptive modality selection algorithm in robot-assisted cognitive training 

    Taranovic, Aleksandar; Jevtic, Aleksandar; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    Interaction of socially assistive robots with users is based on social cues coming from different interaction modalities, such as speech or gestures. However, using all modalities at all times may be inefficient as it can ...
  • Interleaving hierarchical task planning and motion constraint testing for dual-arm manipulation 

    Suárez Hernández, Alejandro; Alenyà Ribas, Guillem; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    In recent years the topic of combining motion and symbolic planning to perform complex tasks in the field of robotics has received a lot of attention. The underlying idea is to have access at once to the reasoning capabilities ...
  • Software tools for the cognitive development of autonomous robots 

    Jimenez Schlegl, Pablo (Richardson Institute - Lancaster University, 2018)
    Conference lecture
    Open Access
    The University of Barcelona, in collaboration with different Spanish and foreign institutions and universities, hosted an international workshop on the ‘Sense and Scope of Autonomy in Emerging Military and Security ...
