A hybrid framework of multiple active appearance models and global registration for 3D prostate segmentation in MRI.
2012
International audience; Real-time fusion of Magnetic Resonance (MR) and Trans Rectal Ultra Sound (TRUS) images aid in the localization of malignant tissues in TRUS guided prostate biopsy. Registration performed on segmented contours of the prostate reduces computational complexity and improves the multimodal registration accuracy. However, accurate and computationally efficient 3D segmentation of the prostate in MR images could be a challenging task due to inter-patient shape and intensity variability of the prostate gland. In this work, we propose to use multiple statistical shape and appearance models to segment the prostate in 2D and a global registration framework to impose shape restri…
Can Health Perceptions, Credibility, and Physical Appearance of Low-Fat Foods Stimulate Buying Intentions?
2020
This study examines the influence of labelling and packaging strategies on perceived product health and overall attitudes to low-fat products in the field of healthy food claims among young consumers. The aim was to determine if these aspects can influence buying intentions. After a literature review, a quantitative study was carried out. With a sample of 300 young consumers (18&ndash
"Me llaman el desaparecido" : coexistencia y continuidad entre la desaparición forzada y la desaparición social
2020
En este trabajo analizo una de las formas del desborde contemporáneo de la categoría de "desaparición", por la cual ésta pasa a designar formas de invisibilidad, exclusión y violencia muy diferentes a la que definía su marco originario. En particular, me detengo en el trazado de una relación de continuidad entre las formas de la desaparición forzada originaria -ejemplificada en el caso emblemático de la dictadura militar chilena- y las formas de "desaparición social" en las democracias liberales contemporáneas. A partir de la puesta en relación de conceptos políticos como campo, doctrina del shock o excepción, y del análisis de algunos productos culturales, exploramos la posibilidad de habl…
Beauty and the Cosmetic Secret
2018
Cosmetic surgery is often linked to the perception that women who resort to cosmetic interventions to alter their physical appearance are vain, superficial, and narcissistic. Few investigations have acknowledged and explored the individual’s personal motivations and experiences of her action and choice with regards to aesthetic surgery. By focusing on subjective experience, alternative insights can be gained on the cosmetic procedure(s) and on how their reshaped body influences an individual’s lifeworld experience. The article explores the perceived benefits and consequences of reshaping, enhancing, and/or reducing a perceived flaw or shortcoming of the body. From this exploration the focus…
Spatio-Chromatic Adaptation via Higher-Order Canonical Correlation Analysis of Natural Images
2014
Independent component and canonical correlation analysis are two general-purpose statistical methods with wide applicability. In neuroscience, independent component analysis of chromatic natural images explains the spatio-chromatic structure of primary cortical receptive fields in terms of properties of the visual environment. Canonical correlation analysis explains similarly chromatic adaptation to different illuminations. But, as we show in this paper, neither of the two methods generalizes well to explain both spatio-chromatic processing and adaptation at the same time. We propose a statistical method which combines the desirable properties of independent component and canonical correlat…
Video-Based Depression Detection Using Local Curvelet Binary Patterns in Pairwise Orthogonal Planes
2016
International audience; Depression is an increasingly prevalent mood disorder. This is the reason why the field of computer-based depression assessment has been gaining the attention of the research community during the past couple of years. The present work proposes two algorithms for depression detection, one Frame-based and the second Video-based, both employing Curvelet transform and Local Binary Patterns. The main advantage of these methods is that they have significantly lower computational requirements, as the extracted features are of very low dimensionality. This is achieved by modifying the previously proposed algorithm which considers Three-Orthogonal-Planes, to only Pairwise-Ort…
Women's preferences for men's facial masculinity are strongest under favorable ecological conditions
2019
AbstractThe strength of sexual selection on secondary sexual traits varies depending on prevailing economic and ecological conditions. In humans, cross-cultural evidence suggests women’s preferences for men’s testosterone dependent masculine facial traits are stronger under conditions where health is compromised, male mortality rates are higher and economic development is higher. Here we use a sample of 4483 exclusively heterosexual women from 34 countries and employ mixed effects modelling to test how social, ecological and economic variables predict women’s facial masculinity preferences. We report women’s preferences for more masculine looking men are stronger in countries with higher so…
Association of bullying victimization with overweight and obesity among adolescents from 41 low‐ and middle‐income countries
2019
Background: Data on the association between overweight/obesity and bullying victimization among adolescents are scarce from low- and middle-income countries. Objectives: We assessed the associations between overweight/obesity and bullying victimization in 41 low- and middle-income countries. Methods: Cross-sectional data from the Global School-based Student Health Survey were analysed. Data on past 30-day bullying victimization (including type) and body mass index based on measured weight and height were collected. The 2007 WHO Child Growth reference was used to define overweight and obesity. Multivariable logistic regression (multinomial and binary) and meta-analyses based on country-wise …
The Self-Concept of Deaf/Hard-of-Hearing and Hearing Students.
2016
The present study investigated the self-concept of deaf and hard-of-hearing (DHH) students in different educational settings compared with those of hearing students in Ethiopia. The research involved a sample of 103 Grade 4 students selected from 7 towns in Ethiopia. They were selected from a special school for the deaf, a special class for the deaf, and a regular school. The Self-Description Questionnaire I ( Marsh, 1990 ) was used to measure the children’s self-concept. The study results indicated that, in comparison with their hearing peers, DHH students had a lower self-concept in the areas of general self, general school, reading, and parental relations. The DHH students in the special…
Body appreciation and body appearance pressure in Norwegian university students comparing exercise science students and other students
2021
Abstract Background Body image is considered a core issue for public health and associates with university students’ overall health. Due to positive associations between exercise and body image, it has been suggested that students within an exercise science program might be more body appreciative compared to other students. On the other hand, the strong societal idealization of the athletic body may expose them to a pressure of having a specific body appearance, which may result in unfavorable health consequences. Nevertheless, studies investigating these hypotheses are lacking. We therefore aimed to explore the level and associations of body appreciation, body appearance pressure, body ima…
