Digital infrared thermal imaging of human skin
IEEE Engineering in Medicine and Biology Magazine, 2002Describes 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, 2000Thermal 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 thermal infrared images
Pattern Recognition, 2013By 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

Eye Localization from Infrared Thermal Images
2013By 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 ...

Airborne Thermal Infrared Hyperspectral Imaging of Gases
2014 6th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2014Characterization 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

Monitoring sympathetic activity by thermal infrared imaging
2010 5th Cairo International Biomedical Engineering Conference, 2010A 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.

Image processing of infrared thermal images for the detection of necrotizing enterocolitis
SPIE Proceedings, 2013Necrotizing Enterocolitis (NEC) is a devastating intestinal disease associated with a high rate of mortality and long-term morbidity. Treatments can be successful if NEC is diagnosed early, but no reliable methods exist. Infrared imaging can detect tissue inflammation and thus has the potential to be an early diagnostic tool for NEC.
