A new pedestrian detection descriptor based on the use of spatial recurrences
Serra Toro, Carlos; Traver Roig, Vicente Javier Springer-Verlag (2011)Recent work on pedestrian detection has relied on the concept of local co-occurences of features to propose higher-order, richer descriptors. While this idea has proven to be benefitial for this detection task, it fails ... -
A review of log-polar imaging for visual perception in robotics
Traver Roig, Vicente Javier; Bernardino, Alexandre Elsevier (2010)Log-polar imaging consists of a type of methods that represent visual information with a space-variant resolution inspired by the visual system of mammals. It has been studied for about three decades and has surpassed ... -
Assisting therapists in assessing small animal phobias by computer analysis of video-recorded sessions
Castelló, Vicente; Traver Roig, Vicente Javier; Serrano-Zárate, Berenice; Montoliu Colás, Raul; Botella, Cristina Springer (2017)Behavioural Avoidance Tests (BATs) are commonly used for assessing phobias. While easy to deploy, these tests have some practical difficulties. For instance, therapists have to make distance estimations that are hard to ... -
Dedicación de los estudiantes en un contexto de aprendizaje cooperativo basado en proyectos: medición, análisis e implicaciones
Traver Roig, Vicente Javier; Pérez Martínez, Juan Manuel Sociedad de la Educación del IEEE (2009-05)Discovering the effort students devote to their studies is of key importance for an appropriate design of courses and syllabus. Although over the last years many studies have been carried out in this respect, few of them ... -
Una experiencia de aprendizaje cooperativo basado en proyectos en una asignatura de diseño de interfaces de usuario
Traver Roig, Vicente Javier Asociación de Enseñantes Universitarios de la Informática (2011)Hoy en día el diseño de la interacción tiene profundas implicaciones en la vida diaria de cada vez más gente. Dado este importante alcance del diseño, las asignaturas de disciplinas relacionadas con la interacción deben ... -
Exploring alternative spatial and temporal dense representations for action recognition
Agustí Ballester, Pau; Traver Roig, Vicente Javier; Pla, Filiberto; Marín Jiménez, Manuel J. Springer-Verlag (2011)The automatic analysis of video sequences with individuals performing some actions is currently receiving much attention in the computer vision community. Among the different visual features chosen to tackle the problem ... -
Exploring early classification strategies of streaming data with delayed attributes
Millán Giraldo, Mónica; Sánchez Garreta, Josep Salvador; Traver Roig, Vicente Javier Springer Verlag (Germany) (2009)In contrast to traditional machine learning algorithms, where all data are available in batch mode, the new paradigm of streaming data poses additional difficulties, since data samples arrive in a sequence and many hard ... -
Log-polar mapping template design: From task-level requirements to geometry parameters
Traver Roig, Vicente Javier; Pla, Filiberto Elsevier (2008)The best parameters defining the geometry of a visual sensor generally depend on the particular visual task the sensor is intended to be used in. However, translating task requirements directly into low-level geometric ... -
Motion Analysis with the Radon Transform on Log-Polar Images
Traver Roig, Vicente Javier; Pla, Filiberto Springer US (2008-02)Image projections provide an effective way of describing image contents or estimate particular kinds of motion. However, most (if not all) of previous literature on projections has been done on Cartesian images. In contrast, ... -
On compiler error messages: what they say and what they mean
Traver Roig, Vicente Javier Hindawi Publishing Corporation (2010)Programmers often encounter cryptic compiler error messages that are difficult to understand and thus difficult to resolve. Unfortunately, most related disciplines, including compiler technology, have not paid much attention ... -
On-line classification of data streams with missing values based on reinforcement learning
Millán Giraldo, Mónica; Traver Roig, Vicente Javier; Sánchez Garreta, Josep Salvador Springer (2011)In some applications, data arrive sequentially and they are not available in batch form, what makes difficult the use of traditional classification systems. In addition, some attributes may lack due to some real-world ... -
On-line learning from streaming data with delayed attributes: A comparison of classifiers and strategies
Millán Giraldo, Mónica; Sánchez Garreta, Josep Salvador; Traver Roig, Vicente Javier Springer (2011-10)In many real applications, data are not all available at the same time, or it is not affordable to process them all in a batch process, but rather, instances arrive sequentially in a stream. The scenario of streaming data ... -
Speeding up the log-polar transform with inexpensive parallel hardware: graphics units and multi-core architectures
Antonelli, Marco; Igual, Francisco; Ramos, Jose Francisco; Traver Roig, Vicente Javier Springer-Verlag (2012)Log-polar imaging is a kind of foveal, biologically inspired visual representation with advantageous properties in practical applications in computer vision, robotics, and other fields. While the cheapest, most flexible, ... -
Three-Dimensional Integral Imaging for Gesture Recognition Under Occlusions
Traver Roig, Vicente Javier; Latorre Carmona, Pedro; Salvador Balaguer, Eva; Pla, Filiberto; Javidi, Bahram Institute of Electrical and Electronics Engineers (IEEE) (2017-02)Over the last years, three-dimensional (3-D) imaging has been applied to human action and gesture recognition, usually in the form of depth maps from RGB-D sensors. An alternative which has not been explored is 3-D integral ...
