Generating thermal facial signatures using thermal infrared images

2012 IEEE International Conference on Emerging Signal Processing Applications, 2012
This paper presents preliminary findings using thermal infrared imaging for the detection of the human face vasculature network at the skin surface and the generation of thermal facial signatures. A thermal infrared camera with reasonable sensitivity provides the ability to image superficial blood vessels on the human skin.

Assessing Drought Responses Using Thermal Infrared Imaging

2016
Canopy temperature, a surrogate for stomatal conductance, is shown to be a good indicator of plant water status and a potential tool for phenotyping and irrigation scheduling. Measurement of stomatal conductance and leaf temperature has traditionally been done by using porometers or gas exchange analyzers and fine-wire thermocouples attached to the ...

A multiplexed silicon infrared thermal imager

TRANSDUCERS '91: 1991 International Conference on Solid-State Sensors and Actuators. Digest of Technical Papers, 1991
The design, fabrication, and testing of a multiplexed infrared thermal imager based on silicon thermopiles is presented. The imager consists of 32 individual thermopile detectors arranged in two linear arrays of 16 elements each. The thermopiles are formed using n/sup +/ polysilicon-gold thermocouples and are supported on 1 mu m-thick dielectric ...

Infrared Detection: Advanced thermal imagers

Physics Bulletin, 1984
Thermal imaging in the 3–5 or 8–12 μ wavebands has come a long way since the early thermograph displays of the 1960s. Today 625-line definition pictures can be obtained from the infrared camera using cadmium mercury telluride (CMT) detectors which compare favourably with normal black and white television.

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.

Atmospheric correction of thermal infrared images

International Journal of Remote Sensing, 1988
Abstract A method for estimating sea surface temperature (SST) from a single infrared (I R) channel together with an atmospheric model is investigated. Based on a simulated atmospheric height profile, the precipitable water and transmittance can be calculated as a function of height from the known atmospheric pressure, temperature and relative humidity

Development of thermal infrared imaging system

SPIE Proceedings, 2013
Development of thermal infrared imaging system has experienced three generations. The main features of every generation are illustrated briefly. The 3 rd thermal imager prototype of the United States is as example. The key techniques are analyzed in detail, which are adopted in the optical system, infrared detector module, control and signal ...

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 construction fault location

SPIE Proceedings, 1990
Over the past few years infrared thermal imaging has been considered for a variety of engineering applications and the potential of this method is only now being realised with the range of applications still increasing (1 and 2). As a totally non-destructive method, it has the advantage of providing handsoff mformation quickly.
