Despite the recent advances in smoke detection from video, detection of smoke from single images is still a challenging problem with both practical and theoretical implications. However, there is hardly any reported research on this topic in the literature. This paper addresses this problem by proposing a novel feature to detect smoke in a single image. An image formation model that expresses a...

We examined prevalence and predictors of comprehensive smoke-free household rules (ie, smoke-free homes and cars) among smokers and nonsmokers in Minnesota. Data came from the 2014 Minnesota Adult Tobacco Survey; weighted analyses consisted of descriptive analyses and multivariate logistic regression analyses. Most adult smokers implemented home-only smoke-free rules (43%) while most nonsmokers...

In this paper, we present a video based smoke detection algorithm based on TVL1 optical flow estimation. The main part of the algorithm is an accumulating system for motion angles and upward motion speed of the flow field. We optimized the usage of TVL1 flow estimation for the detection of smoke with very low smoke density. Therefore, we use adapted flow parameters and estimate the flow field o...

Background: The present systematic review and meta-analysis is designed in order to assess the association between passive and active smoking and lipid profile of children and adolescents. Materials and Methods:  An extensive search was done in databases of Medline, EMBASE, Web of Science, Scopus and CINAHL until October 2017. Two independent researchers screened articles and in the next step, ...

Both microscopic and mesoscopic models use Helbing’s movement model for estimating the characteristics of an evacuation. Because Helbing’s movement model does not consider the effect of smoke, the influence of smoke on walking speed and the toxic gas effect of the combustion gas were used for applying the smoke effect on human behavior. However, these models cannot consider the psychological pr...

The contents of cigarette smoke (gaseous and solid phases) have been attributed to a variety of diseases in the respiratory and cardiovascular systems and have been associated with development of different types of cancers. In respiratory system, these compounds specially cause epithelial cell injury, and interfere with mucocilliary transport (MTC). Various parts of Althea officinalis (family M...

BACKGROUND AND AIM: Oral pigmentation is a condition in which the color of oral mucosa such as gingival mucosa changes. Some exogenous and endogenous factors may lead to oral pigmentation. Secondhand smoke (SHS) or environmental tobacco smoke (ETS) is indirect smoking of an active smoker’s exhalation that can lead to cardiovascular, respiratory system, and some...

Apply the separation principle of the physical contradictions in TRIZ into the simulation of forest fire smoke; propose a forest fire smoke recognition algorithm based on gray bit-plane. To get eight images of moving smoke, the separation process on smoke moving images is necessary; use high-diagram image (the 7th,the 8th image) to extract contours, and extract the contour of the remaining imag...

A global atmospheric general circulation model (GCM) is modified to include radiative transfer parameterizations for the absorption and scattering of solar radiation and the absorption of thermal infrared (IR} radiation by smoke aerosols. The solar scattering modifications include a parameterization for diagnosing smoke optical properties as a function of the timeand spacedependent smoke partic...
