Image Processing Techniques in Thermal and Non-thermal Images
2021Digital thermal imaging (DTI) is a passive, noninvasive, non–ionizing, complimentary diagnostic and real time monitoring technique that enables visualizing and quantifying changes in skin surface temperature. A thermal camera can detect temperature variations in the body, as minute as within 0.1 °C. The image highlights the temperature scale by showing

Broad introduction of thermovision systems in medical practice, and their multifunctional intension make it necessary to find new, more effective ways to processing and analysis of thermal patterns. Acception of these methods in medicine should provide higher diagnostic accuracy and informativeness of thermovision.

Thermal Imaging Aid for the Blind
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006To explore the efficacy of using a far infrared thermal camera with a haptic display to assist blind people in identifying humans, we performed experiments with a prototype device on five low-vision (functionally blind) subjects. Infrared allows for easy detection of human shape due to typically high contrast in temperatures from a person against their

2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics, 2012
The goal of the project is to compile a single picture from a series of shots made by a thermal camera. The reason for that is on the assembled picture it is much easier to examine the workspace important for the user. Because the initial series is shot by the same kind of camera, the traditional four phases can be used for the fusion: detection of ...

Science, 1982
Thermal features on and beneath the surface of a sample can be detected and imaged with a thermal-wave microscope. Various methodologies for the excitation and detection of thermal waves are discussed, and several applications, primarily in microelectronics, are presented.

Clinical Physics and Physiological Measurement, 1990
The association between temperature and disease is centuries old. Clinical thermology was established by Wunderlich, in 1851, who systemically recorded oral temperature with one of the first thermometers capable of reproducible measurement. Thermal imaging is highly developed with contemporary infrared imaging systems having thermal and spatial ...

Thermal diffusivity imaging with the thermal lens microscope
Applied Optics, 2011A coaxial thermal lens microscope was used to generate images based on both the absorbance and thermal diffusivity of histological samples. A pump beam was modulated at frequencies ranging from 50 kHz to 5 MHz using an acousto-optic modulator. The pump and a CW probe beam were combined with a dichroic mirror, directed into an inverted microscope, and ...

Thermal-image quality measurements
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014Thermal image quality assessment is essential in evaluating the performance of thermal imaging systems. The existing no-reference methods can be roughly categorized using quantification measures as follows: a) Human Visual System measures, b) information measures, and c) image distribution measures. All the above classes of measures are not appropriate

This chapter describes an approach to quantifying the local inflammatory response at the injection site after a vaccination by infrared imaging. The aim is to develop a thermographic procedure providing support to evaluate the reactivity of a vaccine. The development of the experimental design had to consider an optimum timeframe for infrared imaging ...
