    • 3D joint speaker position and orientation tracking with particle filters 

      Segura, Carlos; Hernando Pericás, Francisco Javier (2014-01-29)
      Article
      Open Access
      This paper addresses the problem of three-dimensional speaker orientation estimation in a smart-room environment equipped with microphone arrays. A Bayesian approach is proposed to jointly track the location and orientation ...

      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 novel method for low-constrained iris boundary localization 

      Fernández, Carles; Pérez, Dídac; Segura, Carlos; Hernando Pericás, Francisco Javier (2012)
      Conference lecture
      Open Access
      Iris recognition systems are strongly dependent on their segmentation processes, which have traditionally assumed rigid experimental constraints to achieve good performance, but now move towards less constrained environments. ...

    • Accelerating boosting-based face detection on GPUs 

      Oro, David; Fernández, Carles; Segura, Carlos; Martorell Bofill, Xavier; Hernando Pericás, Francisco Javier (2012)
      Conference report
      Restricted access - publisher's policy
      The goal of face detection is to determine the presence of faces in arbitrary images, along with their locations and dimensions. As it happens with any graphics workloads, these algorithms benefit from data-level ...

    • Chatbol, a chatbot for the Spanish “La Liga” 

      Segura, Carlos; Palau, Alex; Luque, Jordi; Ruiz Costa-Jussà, Marta; Banchs, Rafael E. (Springer, 2019-09-25)
      Article
      Open Access
      This work describes the development of a social chatbot for the football domain. The chatbot, named chatbol, aims at answering a wide variety of questions related to the Spanish football league “La Liga”. Chatbol is deployed ...

    • Experimental research on encoder-decoder architectures with attention for chatbots 

      Ruiz Costa-Jussà, Marta; Nuez, Álvaro; Segura, Carlos (2018-03-18)
      Article
      Restricted access - publisher's policy
      Chatbots aim at automatically offering a conversation be- tween a human and a computer. While there is a long track of re- search in rule-based and retrieval-based approaches, the generation-based approaches are promisingly ...

    • GCC-PHAT based head orientation estimation 

      Segura, Carlos; Hernando Pericás, Francisco Javier (2012)
      Conference report
      Open Access
      This work presents a novel two-step algorithm to estimate the orientation of speakers in a smart-room environment equipped with microphone arrays. First the position of the speaker is estimated by the SRP-PHAT algorithm, ...

    • El Método científico en la era de los ordenadores 

      León, C.; Miranda, G.; Rodríguez, C.; Segredo, E.; Segura, Carlos (Universitat Oberta La Salle, 2015-07-08)
      Conference report
      Open Access
      Resumen: En los estudios de grado de las ramas de Ciencias e Ingeniería se suele incluir una asignatura denominada Técnicas Experimentales en la que se introducen los mecanismos de funcionamiento de los aparatos o ...

    • New approaches for iris boundary localization 

      Pérez, Dídac; Fernández, Carles; Segura, Carlos; Hernando Pericás, Francisco Javier (Universidad de las Palmas de Gran Canarias, 2012)
      Conference report
      Open Access
      Iris segmentation is the most determining factor in iris biometrics, which has traditionally assumed rigid constrained environments. In this work, a novel method that covers the localization of the pupillaty and limbic ...

    • Seeing and hearing egocentric actions: how much can we learn? 

      Cartas Ayala, Alejandro; Luque, Jordi; Radeva, Petia; Segura, Carlos; Dimiccoli, Mariella (2019)
      Conference report
      Open Access
      Our interaction with the world is an inherently multi-modal experience. However, the understanding of human-to-object interactions has historically been addressed focusing on a single modality. In particular, a limited ...
