    • A deep analysis on age estimation 

      Huerta Casado, Iván; Fernandez Tena, Carles; Segura, Carlos; Hernando Pericás, Francisco Javier; Prati, Andrea (2015-12-15)
      Article
      Open Access
      The automatic estimation of age from face images is increasingly gaining attention, as it facilitates applications including advanced video surveillance, demographic statistics collection, customer profiling, or search ...
    • 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, ...
    • Background subtraction fusing colour, intensity and edge cues 

      Huerta Casado, Iván; Rowe, Daniel; Viñas, Miguel; Mozerov, Mikhail; Gonzàlez, Jordi (s. n., 2007)
      Conference report
      Open Access
      This paper presents a new background subtraction algorithm for known mobile objects segmentation from a static background scene. Firstly, a casuistry of colour-motion segmentation problems is presented. Our approach first ...
    • Chromatic shadow detection and tracking for moving foreground segmentation 

      Huerta Casado, Iván; Holte, Michael B.; Moeslund, Thomas; Gonzàlez, Jordi (2015)
      Article
      Open Access
      Advanced segmentation techniques in the surveillance domain deal with shadows to avoid distortions when detecting moving objects. Most approaches for shadow detection are still typically restricted to penumbra shadows and ...
    • Exploiting multiple cues in motion segmentation based on background subtraction 

      Huerta Casado, Iván; Amato, Ariel; Roca Marva, Francesc Xavier; González, Jordi (2013)
      Article
      Open Access
      This paper presents a novel algorithm for mobile-object segmentation from static background scenes, which is both robust and accurate under most of the common problems found in motion segmentation. In our first contribution, ...
    • Improving background subtraction based on a casuistry of colour-motion segmentation problems 

      Huerta Casado, Iván; Rowe, Daniel; Mozerov, Mikhail; Gonzàlez, Jordi (Springer Verlag, 2007)
      Part of book or chapter of book
      Open Access
      The basis for the high-level interpretation of observed patterns of human motion still relies on motion segmentation. Popular approaches based on background subtraction use colour information to model each pixel during a ...
    • Moving cast shadows detection methods for video surveillance applications 

      Amato, Ariel; Huerta Casado, Iván; Mozerov, Mikhail; Roca Marva, Francesc Xavier; González Sabaté, Jordi (Springer, 2013)
      Part of book or chapter of book
      Restricted access - publisher's policy
      Moving cast shadows are a major concern in today’s performance from broad range of many vision-based surveillance applications because they highly difficult the object classification task. Several shadow detection methods ...
    • Multimodal feedback fusion of laser, image and temporal information 

      Huerta Casado, Iván; Ferrer Mínguez, Gonzalo; Herrero Cotarelo, Fernando; Prati, Andrea; Sanfeliu Cortés, Alberto (Association for Computing Machinery (ACM), 2014)
      Conference report
      Open Access
      In the present paper, we propose a highly accurate and robust people detector, which works well under highly variant and uncertain conditions, such as occlusions, false positives and false detections. These adverse conditions, ...
    • 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 ...
    • 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)
      Part of book or chapter of book
      Open Access
    • 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 ...
