  • 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 ...
  • 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 ...
  • López Bonal, María Teresa; Fernández Caballero, Antonio; Pérez Jiménez, Rafael; Fernández Graciani, Miguel Ángel (2007)
    Segmentation from optical flow calculation is nowadays a well-known technique for further labeling and tracking of moving objects in video streams. A likely classification of algorithms to obtain optical flow based on the ...
  • 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 ...
  • 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 ...
  • 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 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 Valles, José María; Delgado García, Ana Esperanza; Mira Mira, José; López Bonal, María Teresa; Fernández Graciani, Miguel Ángel (2007)
    Recently, the Algorithmic Lateral Inhibition (ALI) method and the Accumulative Computation (AC) method have proven to be efficient in modelling at the knowledge level for general-motion-detection tasks in video sequences. ...
  • 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; 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 ...

    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 ...
  • López Valles, José María; López Bonal, María Teresa; Fernández Caballero, Antonio; Fernández Graciani, Miguel Ángel (2009)
    Certainly, one of the prominent ideas of Professor Mira was that it is absolutely mandatory to specify the mechanisms and/or processes underlying each task and inference mentioned in an architecture in order to make ...
