    • A hierarchical architecture to multiple target tracking 

      Rowe, Daniel; Huerta Casado, Iván; Perdersoli, Marco; Guinea, Soledad; Gonzàlez, Jordi; Villanueva, Juan J. (s. n., 2007)
      Conference report
      Open Access
      This work presents an architecture based on a modular and hierarchically-organised system to perform Multiple-Target Tracking (MTT). A set of co-operating modules, which work following both bottom-up and top-down paradigms, ...

    • 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 ...

    • Enhancing real-time human detection based on histograms of oriented gradients 

      Perdersoli, Marco; Gonzàlez, Jordi; Chakraborty, Bhaskar; Villanueva, Juan J. (Springer, 2007)
      Part of book or chapter of book
      Open Access

    • HERMES: A research project on human sequence evaluation 

      Gonzàlez, Jordi; Roca, Francesc Xavier; Villanueva, Juan J. (Taylor and Francis, 2007)
      Conference report
      Open Access
      Human Sequence Evaluation concentrates on how to extract descriptions of human behaviour from videos in a restricted discourse domain, such as (i) pedestrians crossing inner-city roads where pedestrians appear approaching ...

    • On reasoning over tracking events 

      Rowe, Daniel; Gonzàlez, Jordi; Huerta Casado, Iván; Villanueva, Juan J. (Springer, 2007)
      Part of book or chapter of book
      Open Access
      High-level understanding of motion events is a critical task in any system which aims to analyse dynamic human-populated scenes. However, current tracking techniques still do not address complex interaction events among ...

    • Robust multiple-people tracking using color-based particle filters 

      Rowe, Daniel; Huerta Casado, Iván; Gonzàlez, Jordi; Villanueva, Juan J. (Springer Verlag, 2007)
      Part of book or chapter of book
      Open Access
      Robust and accurate people tracking is a key task in many promising computer-vision applications. One must deal with non-rigid targets in open-world scenarios, whose shape and appearance evolve over time. Targets may ...
