      Accés obert
      In this paper, we present an object recognition approach that in addition allows to discover intra-class mo dalities exhibiting high-correlated visual information. Unlike to more conventional approaches based on computing ...
    • Object recognition 

      Andrade-Cetto, Juan; Villamizar Vergel, Michael Alejandro (John Wiley & Sons, 2007)
      Capítol de llibre
      Accés obert
      Object recognition entails identifying instances of known objects in sensory data by searching for a match between features in a scene and features on a model. The key elements that make object recognition feasible are the ...
    • 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 ...
    • Online learning and detection of faces with low human supervision 

      Villamizar Vergel, Michael Alejandro; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (Springer, 2019)
      Article
      Accés obert
      We present an efficient,online,and interactive approach for computing a classifier, called Wild Lady Ferns (WiLFs), for face learning and detection using small human supervision. More precisely, on the one hand, WiLFs ...
    • Proactive behavior of an autonomous mobile robot for human-assisted learning 

      Garrell Zulueta, Anais; Villamizar Vergel, Michael Alejandro; Moreno-Noguer, Francesc; Sanfeliu Cortés, Alberto (2013)
      Text en actes de congrés
      Accés obert
      During the last decade, there has been a growing interest in making autonomous social robots able to interact with people. However, there are still many open issues regarding the social capabilities that robots should have ...
    • Random clustering ferns for multimodal object recognition 

      Villamizar Vergel, Michael Alejandro; Garrell Zulueta, Anais; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (2017-09-01)
      Article
      Accés obert
      We propose an efficient and robust method for the recognition of objects exhibiting multiple intra-class modes, where each one is associated with a particular object appearance. The proposed method, called random clustering ...
    • 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 ...
    • Robot interactive learning through human assistance 

      Ferrer Mínguez, Gonzalo; Garrell Zulueta, Anais; Villamizar Vergel, Michael Alejandro; Huerta Casado, Iván; Sanfeliu Cortés, Alberto (Springer Berlin Heidelberg, 2013)

    • 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 ...

      Capítol de llibre
      Accés restringit per política de l'editorial
      This chapter explains an adaptive on-line object detection and classification technique for robust perception due to varying scene conditions, for example partial cast shadows, change on the illumination conditions or ...
    • 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 ...
