Human thermal models for evaluating infrared images

IEEE Engineering in Medicine and Biology Magazine, 2002
Discusses comparing infrared images under various thermal environmental conditions through normalization of skin surface temperature. To evaluate IR images obtained under various thermal environmental conditions, we proposed a human thermal model with which IR images obtained under certain thermal environmental conditions can be converted into images ...

Digital infrared thermal imaging of human skin

IEEE Engineering in Medicine and Biology Magazine, 2002
Describes computational approaches to image processing for improved interpretation and analysis. The authors discuss the physics of image formation, developments in uncooled camera technology, and the use of image processing to interpret 2-D maps of temperatures and to analyze thermal images for assessing physiological changes and responses to physical

Increasing the effective resolution of thermal infrared images

IEEE Engineering in Medicine and Biology Magazine, 2000
Thermal infrared (TIR) imaging is recognized as the most efficient technique for the study of skin temperature distribution. In specific diseases, characteristic changes can be measured from target anatomical sites. In this way, objective noninvasive investigations can be of diagnostic value.

Eye Localization from Infrared Thermal Images

2013
By using the knowledge of facial structure and temperature distribution, this paper proposes an automatic eye localization method from infrared thermal images. A facial structure consisting of 15 sub-regions is proposed to extract Haar-like features. Eight classifiers are learned from the features selected by Adaboost algorithm for left and right eye ...

Infrared Thermal Imaging for Diabetes Detection and Measurement

Journal of Medical Systems, 2019
The diabetes mellititus (type 1) condition occur when the beta cell destroy partially due to autoimmune process. The beta cells produce insulin with respect to blood glucose level. The insulin hormone regulates blood glucose in body. The blood glucose increases in body when insulin secretion is low from pancreas, termed as Diabetes mellititus.

Infrared Imaging Analysis for Thermal Comfort Assessment

2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007
Skin temperature is a relevant and effective indicator for objective evaluation of human sensations and thermal states according to the surrounding thermal stresses. Managed by skin blood flow, sympathetic nervous system (constriction and sweating), subcutaneous thermal structure and facial vein patterns, facial coetaneous temperature variability can ...

Eye localization from thermal infrared images

Pattern Recognition, 2013
By using the knowledge of facial structure and temperature distribution, this paper proposes an automatic eye localization method from long wave infrared thermal images both with eyeglasses and without eyeglasses. First, with the help of support vector machine classifier, three gray-projection features are defined to determine whether a subject is with

Monitoring sympathetic activity by thermal infrared imaging

2010 5th Cairo International Biomedical Engineering Conference, 2010
A novel system that incorporates non-contact and non-invasive physiological monitoring of the human autonomic nervous activity is presented. The autonomic activity is recorded through its effects on cutaneous temperature. The sensing element is a thermal camera that is employed as a computer peripheral.

Airborne Thermal Infrared Hyperspectral Imaging of Gases

2014 6th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2014
Characterization of gas clouds are challenging situations to address due to the uneven distribution of these large entities as a function of time. Whether gas characterization is carried out for gas leaks surveys or environmental monitoring purposes, explosives and/or toxic chemicals are often involved. In such situations, airborne measurements present

Thermal imaging in the extended shortwave infrared band

Applied Optics
The extended shortwave infrared (eSWIR) band, spanning the wavelengths between 2 and 2.6 µm, lies between the traditional reflective and emissive bands. The eSWIR band receives fewer thermal photons from terrestrial targets than the midwave infrared (MWIR) or longwave infrared (LWIR) bands by several orders of magnitude, but ...
