An overview of thermal face recognition methods

Abstract: The popularity of surveillance systems grows as well as a need for better security systems particularly in a bad lighting conditions or at night. The aim of a security system is to collect as many details as possible to enable a better recognition of persons. In this paper, a comparison of representative thermal face recognition methods will be given, emphasizing their strengths and weaknesses. Then, trends in the development of surveillance and security systems will be outlined such as fusion of visible and thermal images and use of convolutional neural networks. Also, existing challenges of thermal facial recognition and its applications in a real world will be pointed out.

Thin-ideal internalization, body dissatisfaction and symptoms of eating disorders in Croatian adolescent girls.

Abstract: The aim of this investigation was to study the relationship between unhealthy eating habits and behaviors, perception and acceptance of societal standards regarding thinness, body dissatisfaction, and family and peer pressure to be thin. One hundred and twentythree high school girls from Rijeka (Croatia) were surveyed using Eating Attitudes Test (EAT-26), Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ), Body Esteem Questionnaire for Adolescents and Adults (BES), and Scale of perceived pressure to be thin from family and peers. The results of path analyses showed that social pressure from family and peers, experience of weight-related teasing and criticism by family members, contributed to development of eating disturbance. The acceptance of social standards related to appearance, contributed to onset of disturbed eating habits. Weight satisfaction alone influences the development of some eating disorder symptoms, but it is also a mediator of higher body mass index (BMI) and internalization of societal appearance standards. Girls with higher BMI, who accepted societal standards of thin-ideal, perceived major social pressure to be thin through direct and persuasive comments designed to establish the importance of dieting, and probably develop eating disturbed habits, or some symptoms of anorexia (AN) or bulimia nervosa (BN).

A Signal Denoising Method Based on the Improved ICI Rule

Abstract: In this letter, we have proposed a signal denoising method based on a modification of the intersection of confidence intervals (ICI) rule. The ICI rule is complemented by the relative intersection of confidence intervals length which is used as an additional criterion for adaptive filter support selection. It is shown that the proposed method outperforms the original ICI method equipped with the local polynomial approximation (LPA), as well as various conventional wavelet shrinkage methods.

Comparison between response dynamics in transition economies and developed economies.

Abstract: In developed economies, the sign of the price increment influences the volatility in an asymmetric fashion— negative increments tend to result in larger volatility!increments with larger magnitudes", while positive increments result in smaller volatility. We explore whether this asymmetry extends from developed economies to European transition economies and, if so, how such asymmetry changes over time as these transition economies develop and mature. We analyze eleven European transition economies and compare the results with those obtained by analyzing U.S. market indices. Specifically, we calculate parameters that quantify both the volatility asymmetry and the strength of its dependence on prior increments. We find that, like their developed economy counterparts, almost all transition economy indices exhibit a significant volatility asymmetry, and the parameter !characterizing asymmetry fluctuates more over time for transition economies. We also investigate how the association between volatility and volatility asymmetry varies by type of market. We test the hypothesis of a negative correlation between volatility and volatility asymmetry. We find that, for developed economies,!experiences local minima during!i"“Black Monday” on October 19, 1987,!ii"the dot-combubble crash in 2002, and!iii"the 2007‐2009 global crisis while for transition economies,!experiences local maxima during times of economic crisis.
