      Projecte/Treball Final de Carrera
      Accés obert
      This project come up from the idea of giving to the current and future domestic robots a tool that allows them to place properly inside a home and adapt their behaviour, adjusting it to the activities and requirements of ...
    • Robust color contour object detection invariant to shadows 

      Scandaliaris, Jorge; Villamizar Vergel, Michael Alejandro; Andrade-Cetto, Juan; Sanfeliu Cortés, Alberto (Springer Verlag, 2007)
      Capítol de llibre
      Accés obert
      In this work a new robust color and contour based object detection method in images with varying shadows is presented. The method relies on a physics-based contour detector that emphasizes material changes and a contour-based ...
    • Semantic segmentation priors for object discovery 

      Martín García, Germán; Husain, Syed Farzad; Schulz, Hannes; Frintrop, Simone; Torras, Carme; Behnke, Sven (IEEE Press, 2016)
      Text en actes de congrés
      Accés obert
      Reliable object discovery in realistic indoor scenes is a necessity for many computer vision and service robot applications. In these scenes, semantic segmentation methods have made huge advances in recent years. Such ...
    • Semi-supervised object detection using SoftTeacher and Transformers 

      Presas Valga, Eric (Universitat Politècnica de Catalunya, 2023-05-30)
      Projecte Final de Màster Oficial
      Accés obert
      This thesis discusses a semi-supervised approach for object detection using a soft-teacher model. The proposed method involves training a student model with both labeled and unlabeled images, using a teacher model to ...
    • Shared random Ferns for efficient detection of multiple categories 

      Villamizar Vergel, Michael Alejandro; Moreno-Noguer, Francesc; Andrade-Cetto, Juan; Sanfeliu Cortés, Alberto (2010)
      Text en actes de congrés
      Accés obert
      We propose a new algorithm for detecting multiple object categories that exploits the fact that different categories may share common features but with different geometric distributions. This yields an efficient detector ...
    • Sistema de reconeixement de gestos facials per a la interacció usuari-ordinador mitjançant visió per computador 

      Martin González, Jose (Universitat Politècnica de Catalunya, 2022-06-28)
