  • Fernández Caballero, Antonio; Mira Mira, José; Fernández Graciani, Miguel Ángel; Gómez Quesada, Francisco Javier (2001)
    The clinical estimate of the foetal weight is probably one of the most difficult parameters to obtain in the prenatal control. Only very accurate foetal body measurements reflect the gestation age and the weight of the ...
  • Mira Mira, José; Fernández Caballero, Antonio; Fernández Graciani, Miguel Ángel; López Bonal, María Teresa; Shirai, Yoshiaki; Sanfeliu, Alberto (2001)
    The problem we are stating is the discrimination of non-rigid objects capable of holding our attention in a scene. Motion allows gradually obtaining all moving objects shapes. We introduce an algorithm that fuses spots ...
  • López Bonal, María Teresa; Fernández Graciani, Miguel Ángel; Mira Mira, José; Fernández Caballero, Antonio (2003)
    In this article, the length?speed ratio (LSR) is proposed as a basic characteristic for the real-time detection of moving objects. We define the LSR of a uniform moving zone as the relation between its length in the direction ...
  • Fernández Caballero, Antonio; López Bonal, María Teresa; Fernández Graciani, Miguel Ángel; Delgado García, Ana E. (2003)
    A model for dynamic visual attention is briefly introduced in this paper. A PSM (problem-solving method) for a generic ?Dynamic Attention Map Generation? task to obtain a Dynamic Attention Map from a dynamic scene is ...
  • Delgado García, Ana E.; Fernández Graciani, Miguel Ángel; Fernández Caballero, Antonio; Mira Mira, José (2003)
    A neural network model called lateral interaction in accumulative computation for detection of non-rigid objects from motion of any of their parts in indefinite sequences of images is presented. Some biological evidences ...
  • Mira Mira, José; Fernández Caballero, Antonio; Fernández Graciani, Miguel Ángel; Delgado García, Ana E. (2003)
    Some of the major computer vision techniques make use of neural nets. In this paper we present a novel model based on neural networks denominated lateral interaction in accumulative computation (LIAC). This model is based ...
  • López Jaquero, Víctor Manuel; Molina Massó, José Pascual; Fernández Caballero, Antonio; González López, Pascual; Montero Simarro, Francisco (Springer-Verlag, 2003)
    For a long time standard desktop applications have ruled the market. Nevertheless, the availability of information has made the user demand new interaction techniques in completely different contexts and devices, but ...
  • Fernández Graciani, Miguel Ángel; Fernández Caballero, Antonio; Mira Mira, José; Delgado García, Ana E. (2003)
    To be able to understand the motion of non-rigid objects, techniques in image processing and computer vision are essential for motion analysis. Lateral interaction in accumulative computation for extracting non-rigid shapes ...
  • Fernández Caballero, Antonio; Montero Simarro, Francisco; González López, Pascual; López Jaquero, Víctor Manuel (2003)
    In this paper we propose to include two up-to-date separate concepts, namely social computing and usability metrics, in intelligent interaction agents to enhance a user-centred, adaptive human-computer interaction (HCI) ...
  • López Bonal, María Teresa; Fernández Caballero, Antonio; Delgado García, Ana E.; Fernández Graciani, Miguel Ángel; Mira Mira, José (2003)
    This paper explores the computational capacity of a novel local computational model that expands the conventional analogical and logical dynamic neural models, based on the charge and discharge of a capacity or in the use ...
  • Fernández Caballero, Antonio; Fernández Graciani, Miguel Ángel; Mira Mira, José; Delgado García, Ana Esperanza (2004)
    In this article knowledge modelling at the knowledge level for the task of moving objects detection in image sequences is introduced. Three items have been the focus of the approach: (1) the convenience of knowledge modelling ...
  • Delgado García, Ana Esperanza; Fernández Caballero, Antonio; López Bonal, María Teresa; Fernández Graciani, Miguel Ángel; Mira Mira, José (2005)
    To be able to understand the motion of non-rigid objects, techniques in image processing and computer vision are essential for motion analysis. Lateral interaction in accumulative computation for extracting non-rigid blobs ...
  • Fernández Graciani, Miguel Ángel; López Bonal, María Teresa; Fernández Caballero, Antonio; Delgado García, Ana Esperanza (2005)
    In this paper a special focus on the relationship between sensitivity and stability in a dynamic selective visual attention method is described. In this proposal sensitivity is associated to short-term memory and stability ...
  • Fernández Caballero, Antonio; Mira Mira, José; Delgado García, Ana Esperanza; López Valles, José María; Fernández Graciani, Miguel Ángel; López Bonal, María Teresa (2005)
    There are several strategies of how to retrieve depth information from a sequence of images, like depth from motion, depth from shading and depth from stereopsis. In this paper, we introduce a new method to retrieve depth ...
  • Molina Massó, José Pascual; López Jaquero, Víctor Manuel; Montero Simarro, Francisco; Fernández Caballero, Antonio; González López, Pascual (2005)
    Nowadays the design of user interfaces has become a discipline of great importance in Software Engineering, mainly due to the increasing impact that a high quality user interface has in the success of a software ...
  • Fernández Caballero, Antonio; González López, Pascual; López Jaquero, Víctor Manuel; Montero Simarro, Francisco; Molina Massó, José Pascual (Springer-Verlag, 2005)
    This work is aimed at the specification of usable adaptive user interfaces. A model-based method is used, which have been proved useful to address this task. A tool is introduced for the specification of user interfaces ...
  • López Valles, José María; Fernández Graciani, Miguel Ángel; Mira Mira, José; López Bonal, María Teresa; Delgado García, Ana Esperanza; Fernández Caballero, Antonio (2005)
    A new method for active visual attention is briefly introduced in this paper. The method extracts motion and shape features from indefinite image sequences, and integrates these features to segment the input scene. The aim ...
  • Mira Mira, José; López Bonal, María Teresa; Delgado García, Ana E.; Fernández Caballero, Antonio; Fernández Graciani, Miguel Ángel (2006)
    In a recent article, knowledge modelling at the knowledge level for the task of moving objects detection in image sequences has been introduced. In this paper, the algorithmic lateral inhibition (ALI) method is now applied ...
  • Delgado García, Ana Esperanza; Fernández Caballero, Antonio; López Bonal, María Teresa; Mira Mira, José; Fernández Graciani, Miguel Ángel (2006)
    This paper describes a method for visual surveillance based on biologically motivated dynamic visual attention in video image sequences. Our system is based on the extraction and integration of local (pixels and spots) as ...
  • Fernández Graciani, Miguel Ángel; Fernández Caballero, Antonio; Delgado García, Ana Esperanza; López Bonal, María Teresa; Mira Mira, José (Elsevier Science, 2006)
    A new computational model for active visual attention is introduced in this paper. The method extracts motion and shape features from video image sequences, and integrates these features to segment the input scene. The aim ...
