  • Object detection and recognition: from saliency prediction to one-shot trained detectors 

    Recasens Continente, Adrià (Universitat Politècnica de Catalunya, 2014-09-03)
    Projecte/Treball Final de Carrera
    Accés obert
    [ANGLÈS] Computer vision capabilities have started to become available in smart devices this last years. The rapid growth of the smartphone world along with the big advance of the computer vision field in the last years ...
  • Object recognition applied to mobile robotics 

    Rigual Aparici, Ferran (Universitat Politècnica de Catalunya, 2012-09-19)
    Projecte/Treball Final de Carrera
    Accés obert
    Investigació de les possibilitats dels mètodes actuals de detecció i reconeixement d'objectes. Adaptació del millor mètode seleccionat (MOPED) per tal de solucionar els problemes de la competició de robots domèstics "Robocup ...
  • Online human-assisted learning using random ferns 

    Villamizar Vergel, Michael Alejandro; Garrell Zulueta, Anais; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (2012)
    Text en actes de congrés
    Accés obert
    We present an Online Random Ferns (ORFs) classifier that progressively learns and builds enhanced models of object appearances. During the learning process, we allow the human intervention to assist the classifier and ...
  • Pedestrian Detection using a boosted cascade of Histogram of Oriented Gradients. 

    Ruiz Sancho, Cristina (Universitat Politècnica de Catalunya, 2014-09-10)
    Projecte/Treball Final de Carrera
    Accés obert
    [ANGLÈS] Pedestrian detection has been an active area of research in recent years; its interest relies on the potential positive impact on quality of life of the related applications (surveillance systems, automotive safety, ...
  • Real time people detection combining appearance and depth image spaces using boosted random ferns 

    Vaquero Gómez, Víctor; Villamizar Vergel, Michael Alejandro; Sanfeliu Cortés, Alberto (Springer, 2015)
    Text en actes de congrés
    Accés obert
    This paper presents a robust and real-time method for people detection in urban and crowed environments. Unlike other conventional methods which either focus on single features or compute multiple and independent classifiers ...
  • Recognizing point clouds using conditional random fields 

    Husain, Syed Farzad; Dellen, Babette Karla Margarete; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Text en actes de congrés
    Accés obert
    Detecting objects in cluttered scenes is a necessary step for many robotic tasks and facilitates the interaction of the robot with its environment. Because of the availability of efficient 3D sensing devices as the Kinect, ...
  • Robots domésticos: reconocimiento de estancias mediante detección de objetos 

    Cots Prat, Joan (Universitat Politècnica de Catalunya, 2016-07-22)
    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 ...
  • 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 ...
  • Very fast solution to the PnP problem with algebraic outlier rejection 

    Ferraz Colomina, Luis; Binefa, Xavier; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Text en actes de congrés
    Accés obert
    We propose a real-time, robust to outliers and accurate solution to the Perspective-n-Point (PnP) problem. The main advantages of our solution are twofold: first, it integrates the outlier rejection within the pose estimation ...
