Humans have distinctive and unique traits which can be used to distinguish them from other humans, acting as a form of identification. A number of traits characterising physiological or behavioral characteristics of human can be used for biometric identification. Basic physiological characteristics are face, facial thermograms, fingerprint, iris, retina, hand geometry, odour/scent. Voice, signa...

In the modern world, a reliable personal identification infrastructure is required to control the access in order to secure areas or materials. Conventional methods of recognizing the identity of a person by using passwords or cards are not altogether reliable, because they can be forgotten, stolen, disclosable, or transferable (Zhang, 2000). Biometric technology, which is based on physical and...

skin and hair, and is synthesized in melanosomes transferred from melanocytes. Although melanin plays an important protective role against UV light, over production and accumulation of melanin pigment it could create serious skin problems such as freckles, age spots, and melasma. Thus, the inhibition of melanogenesis has been the focus of medicinal and cosmetic treatments for skin depigmenting ...

IN the present article an account is given of a skin disease with ocular manifestations. At the beginning the skin disease was diagnosed as lentigenes and the eye-affection was suggested to be a melanoma bulbi. Observation of the clinical picture, however, and later familial investigations, gave clear evidence of a close connection between the two affections, and the condition became recognised...

layer of the dermis and is the major cellular component responsible for skin color. Although normal melanin pigmentation in the skin is the major defense mechanism against ultraviolet light, the production of abnormal pigmentation such as melasma, freckles, senile lentigines, and other forms of melanin hyperpigmentation can be a serious problem aesthetically. The novo synthesis of melanin invol...

The scope of this thesis is threefold: design and construction of a 3D facial scanning system, development of a practical reflection model describing reflectance properties of human skin, and an analysis of facial appearance of multiple subjects, leading to intuitive editing operations for the skin model. The scanning system consists of two devices that separately acquire surface reflectance an...

BACKGROUND There is an 'epidemic' increase in skin cancers worldwide in white-skinned populations. Australia has the highest incidence of skin cancer in the world despite intensive publicity in the last 30 years aimed at prevention. AIM This study set out to assess risk factors, knowledge and preventive behaviour relevant to skin cancer in general practice patients in South Australia, and to ...

CMAJ • NOVEMBER 23, 2010 • 182(17) © 2010 Canadian Medical Association or its licensors E802 With the increased understanding of the effects of vitamin D on the body and the growing evidence that people living in northern climes have inadequate levels of vitamin D during the winter months, I wondered whether I should be prescribing sunlight for my patients. After all, a mild sunburn after 5 to ...

Using a metric feature space for pattern recognition, data mining, and machine learning greatly simplifies the mathematics because distances are preserved under rotation and translation in feature space. A metric space also provides a “ruler”, or absolute measure of how different two feature vectors are. In the computer vision community color can easily be misstreated as a metric distance. This...

A 29-year-old male Caucasian presented with a 5-month history of left anterior chest pain and dyspnoea. There was no associated cough, haemoptysis, fever, weight loss or night sweats. He was a never smoker with no previous exposure to asbestos. On general examination, he had multiple freckles and tattoos. His lower left chest wall was tender on palpation but no other abnormalities were present....
