Field test studies of our infrared-based human temperature screening system embedded with a parallel measurement approach

Validity of inner canthus temperature recorded by infrared thermography as a non-invasive surrogate measure for core temperature at rest, during exercise and recovery

“…2a). Studies of Ng et al (2004), Sumriddetchkajorn and Chaitavon (2009) and Teunissen and Daanen (2011) also registered T EC comparing with other gold standard methods showing also smaller values than for T C as the obtained in our study. For example, in the moment R15 there was a difference of 0.6°C, being T EC (36.6°C) and T C (37.2°C).…”

“…The aim of the works of Ng et al (2004) and Sumriddetchkajorn and Chaitavon (2009) was to test the validity of the T EC to detect people with fever and the method used for evaluation of T C was the ear thermometer. In these two studies, the authors concluded that the T EC can be used as a measure for the detection of fever.…”

Fever screening of seasonal influenza patients using a cost-effective thermopile array with small pixels for close-range thermometry

“…This approach has been used and generally approved in some recent studies on the evaluation of thermography systems. 4,5 By using the axillary temperature as the reference, the axillary temperatures of 36/155 febrile patients were >37.5 8C. The sensitivity and specificity were 80.5% and 93.3%, respectively, for setting the threshold cut-off of maximum facial temperature at 36.5 8C.…”

Fever detection for dynamic human environment using sensor fusion

“…higher the temperature, the higher is the pixels intensity). In this case the location of face regions in the infrared images can be determined by some simple image processing techniques such as temperature thresholding (30-42 C) and morphological processing (a method for extracting requested image components) [30][31] [28].…”
