Motion estimation for highly dynamic phenomena such as smoke is an open challenge for Computer Vision. Traditional dense motion estimation algorithms have difficulties with non-rigid and large motions, both of which are frequently observed in smoke motion. We propose an algorithm for dense motion estimation of smoke. Our algorithm is robust, fast, and has better performance over different types...

Estimating the sex of skeletal remains is critical in creating the biological profile of an adult individual. Previous research has shown that analyzing the sternum may lead to an accurate estimation of sex based on studies performed on various populations around the globe, such as Indian, European, African, Canadian and North American. The motivation of the current study is to develop classifi...

Pose estimation in the context of human motion analysis is the process of approximating the body configuration in each frame of a motion sequence. We propose a novel pose estimation method based on fitting a skeletal model to tree structures built from skeletonised visual hulls reconstructed from multi-view video. The pose is estimated independently in each frame, hence the method can recover f...

The degree of fusion at the anterior aspect of the sacral vertebrae has been scored in 242 male and female skeletons from the Lisbon documented collection, ranging from 16 to 59 years old in age. Statistical tests indicate a sex difference towards earlier fusion in young females compared with young males, as well as a clear association between degree of fusion and age. Similar results have been...

Age estimation is a critical component of the biological profile in forensic and bioarchaeological contexts. The majority of age estimation methods are most accurate for individuals of younger age cohorts, typically those under 40 years of age. Skeletal degeneration can vary greatly between individuals, making age estimation less accurate for adult individuals. While there are some methods that...

There is a high prevalence of rib fractures in human remains from archeological contexts, but these are seldom the focus paleopathological studies pertaining skeletal trauma. This study aims to document fracture patterns Coimbra Identified Skeletal Collection, Department Life Sciences, University Coimbra. Specific this included estimation 252 individuals, both sexes (females: 128; males: 124), ...

In order to solve the problem of difficult and low precision in detection safety helmet wearing complex pose construction worker, a method based on estimation is proposed. model OpenPose, residual network optimized feature extraction introduced obtain skeletal point information then worker estimated information, three-point localization proposed for front back pose, skin colour side determine h...

valproic acid is one of the main antiepileptic drugs. there is an increased risk of neural tube defects and axial skeletal malformations among infants born to women who had received valproic acid. there is a hypothesis that one biochemical abnormality underlying the teratogenicity of valproic acid is a drug-induced reduction in maternal plasma zinc .in the present experimental study mated rats ...

skeletal deformities are a common problem in fish hatcheries and commercial farms that affect growth, development and survival as well as the market value of the final product. among the nutritional components, phosphorus (p) and calcium (ca) are of special interest as they are directly involved in the development and maintenance of the skeletal system. hence, the present study was carried out ...
