Ethical issues in topical computer vision applications
2017
Computer vision is a research area that contains multiple methods to approach numerous visual problems. In the past decade, it has been rapidly evolving with the introduction of many new technologies and applications that utilize different computer vision techniques. The purpose of this study is to identify the ethical issues that concern recent trending computer vision applications and their tasks. This was done by conducting an integrative literature review and synthesizing various studies that have been conducted on the different applications of computer vision and their ethical issues. The result was a synthesized framework of different ethics themes that relate to the different areas o…
Differences in Chromatic Sensitivity Estimated Using Static and Dynamic Colour Stimuli
2017
Abstract The current study reports on a novel computerised colour vision test employing static and dynamic stimuli. The aim of the study was to assess if static and dynamic stimuli result in comparable chromatic discrimination thresholds when participant’s age is taken into account. Participants (n = 20) were 21 to 77 years old, had normal colour vision and no history of any eye disease. They all participated in two sessions estimating chromatic sensitivity with static and dynamic stimuli, respectively, with six directions in colour space varying either along the red-green (RG) or yellow- blue (YB) directions. We found no significant differences in chromatic thresholds along a tritan axis o…
La integración de la Atención a la Dependencia en los Servicios Sociales Municipales del Ayuntamiento de Sagunto
2011
El cuarto Pilar del Bienestar Social es el sistema de Servicios Sociales, la atención a la dependencia debería ser considerada un subsistema del sistema de Servicios Sociales, el catalogo de prestaciones que recoge la Ley de Autonomía Personal y Atención a las Personas en Situación de Dependencia (Ley 39/2006) se corresponde con las prestaciones reconocidas en las leyes de servicios sociales de las diferentes Comunidades Autónomas, todas ellas aprobadas con anterioridad a la Ley 39/2006. La implantación por parte de la Generalitat Valenciana de la Ley de atención a la dependencia puede vulnerar el principio de Autonomía Local recogido en varios marcos normativos. La visión de atención integ…

La crise des intellectuels et ses avatars dans "Les Mandarins" de Simone de Beauvoir
2022
In the novel The Mandarins, Simone de Beauvoir shows the crisis of French intellectuals, namely writers facing ideological and political dilemmas after World War Two. Reflecting on the usefulness of their works, the main protagonists ask the fundamental question, namely why / for what to write and act. In the writer’s optics, two solutions are possible. On the one hand, the commitment, and the need for being aware of situations and actions. On the other hand, the idea of the autonomy of literature. This opposition seems to cause a failure of common expectations and hopes, conformism, collapse of values as well as love failures. The history of “broken illusions” of a known milieu allows the …
Universal Patterns in Color-Emotion Associations Are Further Shaped by Linguistic and Geographic Proximity
2020
Many of us “see red,” “feel blue,” or “turn green with envy.” Are such color-emotion associations fundamental to our shared cognitive architecture, or are they cultural creations learned through our languages and traditions? To answer these questions, we tested emotional associations of colors in 4,598 participants from 30 nations speaking 22 native languages. Participants associated 20 emotion concepts with 12 color terms. Pattern-similarity analyses revealed universal color-emotion associations (average similarity coefficient r = .88). However, local differences were also apparent. A machine-learning algorithm revealed that nation predicted color-emotion associations above and beyond tho…
Curvelet-based method for orientation estimation of particles from optical images
2014
A method based on the curvelet transform is introduced to estimate the orientation distribution from two-dimensional images of small anisotropic particles. Orientation of fibers in paper is considered as a particular application of the method. Theoretical aspects of the suitability of this method are discussed and its efficiency is demonstrated with simulated and real images of fibrous systems. Comparison is made with two traditionally used methods of orientation analysis, and the new curvelet-based method is shown to perform better than these tradi- tional methods. peerReviewed
Predicting the availability of users' devices in Decentralized Online Social Networks
2018
The understanding of the user temporal behavior is a crucial aspect for all those systems that rely on user resources for daily operations, such as decentralized online social networks (DOSNs). Indeed, DOSNs exploit the devices of their users to take on and share the tasks needed to provide services such as storing the published data. In the last years, the increasing popularity of DOSN services has changed the way of how people interact with each other by enabling users to connect to these services at any time by using their personal devices (such as notebooks or smartphones). As a result, the availability of data in these systems is strongly affected (or reflected) by the temporal behavio…
Computational Modeling of Human Visual Function using Psychophysics, Deep Neural Networks, and Information Theory
2023
Visual perception is a key to unlocking the secrets of brain functions because most of the information is processed through the early visual system and then transmitted to the high-level cognitive perception brain regions. The brain functions as a self-organizing, bio-dynamic, and chaotic system that receives outside information and then decomposes it into pieces of information that can be processed efficiently and independently. The work connects natural image statistics, psychophysics, deep neural networks, and information theory to perceptual vision systems to explore how vision processes information from the outside world and how the information coupled drives functional connectivity be…
Détection robuste de mouvement par histogrammes quasi‐continus
2012
National audience; Dans cet article, nous proposons d'utiliser la représentation de distributions de valeurs par histogrammes quasi-continus pour réaliser une détection temps réel de mouvement dans une séquence d'images. Nous comparons les résultats de cette détection à deux méthodes de référence de la littérature.
