OmniFlowNet: a Perspective Neural Network Adaptation for Optical Flow Estimation in Omnidirectional Images

2021

International audience; Spherical cameras and the latest image processing techniques open up new horizons. In particular, methods based on Convolutional Neural Networks (CNNs) now give excellent results for optical flow estimation on perspective images. However, these approaches are highly dependent on their architectures and training datasets. This paper proposes to benefit from years of improvement in perspective images optical flow estimation and to apply it to omnidirectional ones without training on new datasets. Our network, OmniFlowNet, is built on a CNN specialized in perspective images. Its convolution operation is adapted to be consistent with the equirectangular projection. Teste…

Part 1—You can run but you can't hide: Intrusive thoughts on six continents

2014

Abstract Most cognitive approaches for understanding and treating obsessive-compulsive disorder (OCD) rest on the assumption that nearly everyone experiences unwanted intrusive thoughts, images and impulses from time to time. These theories argue that the intrusions themselves are not problematic, unless they are misinterpreted and/or attempts are made to control them in maladaptive and/or unrealistic ways. Early research has shown unwanted intrusions to be present in the overwhelming majority of participants assessed, although this work was limited in that it took place largely in the US, the UK and other ‘westernised’ or ‘developed’ locations. We employed the International Intrusive Thoug…

Cannabis, cerebro y adicción

2005

El compuesto psicoactivo de la cannabis sátiva, el í-9-tetrahidrocannabinol, ejerce sus efectos sobre el sistema nervioso central a través del receptor cannabinoide CB1. La localización presináptica del receptor CB I sugiere una función de modulación de la liberación de neurotransmisores a través de la denominada señalización retrógrada. El THC actúa en el sistema de recompensa cerebral de una manera muy similar a la de otras sustancias adictivas, incluyendo tanto la capacidad de generar tolerancia y síndro­ me de abstinencia como la interacción con otros sistema de neurotransmisión implica­ dos en el fenómeno de la recompensa. El consumo de cannabis provoca, al menos de manera transitoria,…

Judging body weight from faces: the height-weight illusion.

2012

Being able to exploit features of the human face to predict health and fitness can serve as an evolutionary advantage. Surface features such as facial symmetry, averageness, and skin colour are known to influence attractiveness. We sought to determine whether observers are able to extract more complex features, namely body weight. If possible, it could be used as a predictor for health and fitness. For instance, facial adiposity could be taken to indicate a cardiovascular challenge or proneness to infections. Observers seem to be able to glean body weight information from frontal views of a face. Is weight estimation robust across different viewing angles? We showed that participants stron…

What is the Right Mix? Toward a Compensatory Theory of Employer Attractiveness

2021

Despite its long history, employer attractiveness research so far has almost exclusively studied large corporate firms and focused on the question which employer benefits influence firms’ employer attractiveness. However, we know only little about to what extent these findings generalize to more resource-constrained firms, such as small companies and start-ups. To address this void in the literature, this study integrates the theory of instrumental-symbolic employer benefits with a neo-configurational perspective to propose and test a compensatory theory of employer attractiveness that explains how start-ups achieve high employer attractiveness. Using set-theoretic methods, we analyze 219 s…

Mate preferences in Argentinean transgender people

2018

Transgender people provide a unique opportunity to examine the effect of biological sex versus gender identity on mating preferences. This study aimed at identifying the mate characteristics that are most and least valued by transgender people and at examining to what extent their biological sex or their gender identity determined their mate preferences. A convenience sample of 134 male‐to‐female (MTF) and 94 female‐to‐male (FTM) individuals from Argentina rated Buss's list of 18 mate attributes. Compared to FTM, MTF individuals placed significantly more emphasis on attractiveness and socioeconomic status, whereas FTM, more than MTF individuals, valued partners with a dependable character. …

Sex differences in mate preferences across 45 countries: a large-scale replication

2020

Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives-an evolutionary psychological perspective and a biosocial role perspective-offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the literature is fraught with conflicting methods, analyses, results, and conclusions. Using a new 45-country sample (N = 14,399), we attempted to replicate classic studies and test both the evolutionary and biosocial role perspectives. Support for unive…

Metodi per la ricostruzione virtuale e la visualizzazione di opere d'architettura perdute

2022

Digital technologies for architecture representation have strongly modified uses and rules inherited from a millennial tradition. In the initial development period CAD tools worked as electronic drafting machines and digital drawings were almost similar to hand-made drawings; plans, fronts, sections and the like. In this period perspective and axonometric drawings were rarely executed because architects realized that these drawings had to be substituted by 3D digital models views, but modeling tools were not so familiar to professionals, both for software and hardware limitations. The evolution of architecture digital representation is still in progress, but it is possible to outline a prec…

Intellectual property from a labour law perspective: the transfer of authors' rights in labour relationships

2020

This article analyses Spanish intellectual property law to establish whether formalised employment contracts are associated with the transfer to employers of the economic rights to works created by employees. This analysis is limited to the legal treatment of employee-created literary, artistic and scientific works, which are subject to authors' rights and are protected by intellectual property law. The study does not include inventions created in a labour relationship, which are regulated by legislation on patents and brands, and are thus dealt with differently according to industrial property rights.

THE INFLUENCE OF SPATIAL COGNITION IN THEORY OF MIND AND CENTRAL COHERENCE TASKS: STUDY IN AUTISM

Autism Spectrum Disorder (ADS) is a severe developmental disability characterized by impairments in social interaction and communicative skills. Despite a growing research interest in the field, the causes of these impairments remain unknown. Two lines of research, Theory of Mind (ToM) and Central Coherence (CC), using experimental tasks such as visuo-spatial perspective Taking (VPT) and the local and global levels have suggested that visuo-spatial attention and spatial variables in the self-versus other recognition, may be the basis of the cognitive processes underlying social interaction. According to spatial attention, such as observed in the Unilateral spatial neglect (USN) may contribu…
