Accurate pupil center detection in off-the-shelf eye tracking systems using convolutional neural networks
Larumbe Bergera, Andoni
; Garde Lecumberri, Gonzalo ; Porta Cuéllar, Sonia ; Cabeza Laguna, Rafael ; Villanueva Larre, Arantxa (MDPI, 2021)
Artículo / Artikulua 
Remote eye tracking technology has suffered an increasing growth in recent years due to its applicability in many research areas. In this paper, a video-oculography method based on convolutional neural networks (CNNs) for ... -
Exact inter-discharge interval distribution of motor unit firing patterns with gamma model
Navallas Irujo, Javier ; Porta Cuéllar, Sonia ; Malanda Trigueros, Armando (Springer, 2019)
Artículo / Artikulua
Inter-discharge interval distribution modeling of the motor unit firing pattern plays an important role in electromyographic decomposition and the statistical analysis of firing patterns. When modeling firing patterns ... -
Gaze tracking system model based on physical parameters
Villanueva Larre, Arantxa ; Cabeza Laguna, Rafael ; Porta Cuéllar, Sonia (World Scientific Publishing, 2007)
Artículo / Artikulua
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 ; Ponz Sarvisé, Victoria; Sesma Sánchez, Laura ; Ariz Galilea, Mikel ; Porta Cuéllar, Sonia ; Cabeza Laguna, Rafael (ACM (Association for Computing Machinery), 2013)
Artículo / Artikulua
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 ; Larumbe Bergera, Andoni ; Ariz Galilea, Mikel ; Porta Cuéllar, Sonia ; Cabeza Laguna, Rafael ; Villanueva Larre, Arantxa (IEEE, 2020)
Artículo / Artikulua

Low-cost eye tracking calibration: a knowledge-based study
Garde Lecumberri, Gonzalo; Larumbe Bergera, Andoni ; Bossavit, Benoît ; Porta Cuéllar, Sonia ; Cabeza Laguna, Rafael ; Villanueva Larre, Arantxa (MDPI, 2021)
Artículo / Artikulua
Subject calibration has been demonstrated to improve the accuracy in high-performance eye trackers. However, the true weight of calibration in off-the-shelf eye tracking solutions is still not addressed. In this work, a ... -
Relevance of sex, age and gait kinematics when predicting fall-risk and mortality in older adults
Porta Cuéllar, Sonia ; Martínez Ramírez, Alicia ; Millor Muruzábal, Nora ; Gómez Fernández, Marisol ; Izquierdo Redín, Mikel (Elsevier, 2020)
Artículo / Artikulua
Approximately one-third of elderly people fall each year with severe consequences, including death. The aim of this study was to identify the most relevant features to be considered to maximize the accuracy of a logistic ... -
Sliding window averaging in normal and pathological motor unit action potential trains
Malanda Trigueros, Armando ; Navallas Irujo, Javier ; Rodríguez Falces, Javier ; Porta Cuéllar, Sonia ; Fernández Martínez, Miguel (Elsevier, 2018)
Artículo / Artikulua
Objective: To evaluate the performance of a recently proposed motor unit action potential (MUAP) averaging method based on a sliding window, and compare it with relevant published methods in normal and pathological muscles. ...
