  • Boosting histograms of oriented gradients for human detection 

    Perdersoli, Marco; Gonzàlez, Jordi; Chakraborty, Bhaskar; Villanueva, Juan J. (s. n., 2007)
    Conference report
    Open Access
    In this paper we propose a human detection framework based on an enhanced version of Histogram of Oriented Gradients (HOG) features. These feature descriptors are computed with the help of a precalculated histogram of ...
  • Evaluation of three vision based object perception methods for a mobile robot 

    Ramisa Ayats, Arnau; Aldavert Miró, David; Vasudeban, Shrihari; Toledo Morales, Ricardo; López de Mantaras, Ramon (2012)
    Article
    Open Access
    This paper addresses visual object perception applied to mobile robotics. Being able to perceive household objects in unstructured environments is a key capability in order to make robots suitable to perform complex tasks ...
  • GPU-based low-level image processing for object recognition using HDR images 

    Dominguez Tejera, Jonatan (Universitat Politècnica de CatalunyaKarlsruher Institut für Technology, 2012-06-15)
    Master thesis (pre-Bologna period)
    Open Access
    [ANGLÈS] The algorithm developed for object recognition using HDR images is divided in 3 modules. The first one obtain images without noise from the scene using a fusion method, which one is based on the pdf of each pixel ...
  • Object detection and recognition: from saliency prediction to one-shot trained detectors 

    Recasens Continente, Adrià (Universitat Politècnica de Catalunya, 2014-09-03)
    Master thesis (pre-Bologna period)
    12 months embargo
    [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)
    Master thesis (pre-Bologna period)
    Open Access
    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)
    Conference report
    Open Access
    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 ...
  • Optimization of robust loss functions for weakly-labeled image taxonomies 

    McAuley, Julian J.; Ramisa Ayats, Arnau; Caetano, Tibério S. (2013)
    Article
    Restricted access - publisher's policy
    The recently proposed ImageNet dataset consists of several million images, each annotated with a single object category. These annotations may be imperfect, in the sense that many images contain multiple objects belonging ...
