    • Evaluation of accurate eye corner detection methods for gaze estimation 

      Bengoechea Irañeta, José Javier; Cerrolaza Martínez, Juan José; Villanueva Larre, Arantxa Upna; Cabeza Laguna, Rafael Upna (Bern Open Publishing, 2014)   Artículo / Artikulua  OpenAccess
      Accurate detection of iris center and eye corners appears to be a promising approach for low cost gaze estimation. In this paper we propose novel eye inner corner detection methods. Appearance and feature based segmentation ...
    • Fast and robust ellipse detection algorithm for head-mounted eye tracking systems 

      Martinikorena Aranburu, Ion Upna; Cabeza Laguna, Rafael Upna; Villanueva Larre, Arantxa Upna; Urtasun, Iñaki; Larumbe Bergera, Andoni (Springer, 2018)   Artículo / Artikulua  OpenAccess
      In head-mounted eye tracking systems, the correct detection of pupil position is a key factor in estimating gaze direction. However, this is a challenging issue when the videos are recorded in real-world conditions, due ...
    • Gaze tracking system model based on physical parameters 

      Villanueva Larre, Arantxa Upna; Cabeza Laguna, Rafael Upna; Porta Cuéllar, Sonia Upna (World Scientific Publishing, 2007)   Artículo / Artikulua  OpenAccess
      In the past years, research in eye tracking development and applications has attracted much attention and the possibility of interacting with a computer employing just gaze information is becoming more and more feasible. ...
    • Hybrid method based on topography for robust detection of iris center and eye corners 

      Villanueva Larre, Arantxa Upna; Ponz Sarvisé, Victoria; Sesma Sánchez, Laura Upna; Ariz Galilea, Mikel Upna; Porta Cuéllar, Sonia Upna; Cabeza Laguna, Rafael Upna (ACM (Association for Computing Machinery), 2013)   Artículo / Artikulua  OpenAccess
      A multi-stage procedure to detect eye features is presented. Multiresolution and topographic classification are used to detect the iris center. The eye corner is calculated combining valley detection and eyelid curve ...
    • Low cost gaze estimation: knowledge-based solutions 

      Martinikorena Aranburu, Ion Upna; Larumbe Bergera, Andoni; Ariz Galilea, Mikel Upna; Porta Cuéllar, Sonia Upna; Cabeza Laguna, Rafael Upna; Villanueva Larre, Arantxa Upna (IEEE, 2020)   Artículo / Artikulua
      Eye tracking technology in low resolution scenarios is not a completely solved issue to date. The possibility of using eye tracking in a mobile gadget is a challenging objective that would permit to spread this technology ...
    • Robust and accurate 2D-tracking-based 3D positioning method: application to head pose estimation 

      Ariz Galilea, Mikel Upna; Villanueva Larre, Arantxa Upna; Cabeza Laguna, Rafael Upna (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      Head pose estimation (HPE) is currently a growing research field, mainly because of the proliferation of human–computer interfaces (HCI) in the last decade. It offers a wide variety of applications, including human behavior ...
