Thermal infrared imaging has been proposed as a potential system for the computational assessment of human autonomic nervous activity and psychophysiological states in a contactless and noninvasive way. Through bioheat modeling of facial thermal imagery, several vital signs can be extracted, including localized blood perfusion, cardiac pulse, breath rate, and sudomotor response, since all these...

Infrared thermal imaging (IRT) is a non-invasive, non-contact technique which allows one to measure and visualize infrared radiation. In medicine, thermal imaging has been used for more than 50 years in various clinical settings, including Raynaud's phenomenon and systemic sclerosis. Imaging and quantification of surface body temperature provides an indirect measure of the microcirculation's ov...

Conventional diagnostic modalities for assessing arterial circulation or tissue perfusion include blood pressure measurement, ultrasound evaluation, and contrast-based angiographic assessment. An infrared thermal camera can detect infrared radiation energy from the human body, which generates a thermographic image to allow tissue perfusion analysis. We describe a smartphone-based miniature ther...

Recent research has demonstrated distinct advantages of using thermal infrared imaging for improving face recognition performance. While conventional video cameras sense reflected light, thermal infrared cameras primarily measure emitted radiation from objects such as faces. Visible and thermal infrared image data collections of frontal faces have been on-going at NIST for over two years, produ...

COMMERCIAL VISION SYSTEMS In the last few years thermal imaging has found its way into many more commercial applications. Most of these applications require a low cost product with an uncooled detector. These sensors image in the LWIR, or longwave infrared band (7 14 μm). Different types of uncooled detectors are available on the market. Since the infrared detector is the heart of any thermal i...

In thermal imaging, the invisible radiation pattern of an object is converted into a visible image. This two-dimensional temperature mapping technique has potential for characterizing products during several operations of agricultural and food industries. Thermal imaging has been successfully adopted for studying plant physiology, irrigation scheduling, and yield forecasting in agricultural fie...

INTRODUCTION Infrared thermal imaging (thermography) is a non-invasive method to measure skin temperature. The primary aim of this study was to examine the feasibility of thermography for the assessment of abdominal skin temperature in extremely low birthweight (ELBW) infants, with secondary aims to compare abdominal and thoracic skin temperature, and to explore potential relationships between ...

BACKGROUND This study was performed to assess the photothermal response of highly focused laser energy using infrared thermal imaging instrument to detect and assess the actual temperature distribution during flash lamp pumped pulsed dye laser (FLPPDL) treatment for port wine stain (PWS) patients and avoiding its complications. METHODS A retrospective review of 40 patients with PWS birthmark ...

Face recognition is a wide area having many techniques to achieve the same. The aim of the paper is to introduce Thermal Imaging and to study how it can be used for facial recognition and also for deception detection. This paper looks into the single modal and multi modal face recognition techniques involving infrared (IR) imaging. It then moves to analyze facial variations to study deception u...
