    • 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 ...
