Infrared Images of Natural Subjects
Applied Optics, 1968Images of a number of natural subjects have for some time been made using wavelengths longer than those to which film is sensitive. This has been done by use of instruments employing mechanical scanning and cooled semiconductor detectors. Some of this imagery is now becoming available for general use.

Near infrared imaging with nanoparticles
WIREs Nanomedicine and Nanobiotechnology, 2010AbstractNear infrared imaging has presented itself as a powerful diagnostic technique with potential to serve as a minimally invasive, nonionizing method for sensitive, deep tissue diagnostic imaging. This potential is further realized with the use of nanoparticle (NP)‐based near infrared (NIR) contrast agents that are not prone to the rapid ...

Matching of infrared and visible images
2012 9th International Conference on Fuzzy Systems and Knowledge Discovery, 2012A new matching method based on improved Nonsubsampled contourlet transform (NSCT) is put forward to solve the problem of low matching precision in matching of infrared and visible images. Firstly, improved NSCT is introduced; then, improved NSCT disassembly is done; next, energy at each little region is calculated to compose circumcircle.

Biomedical infrared imaging in Japan
IEEE Engineering in Medicine and Biology Magazine, 1998We discuss the present state of biomedical infrared imaging in Japan as well as strategies for future growth. We review the systems currently being used here and the extent of their use. We also address the professional and cultural preconceptions that must be overcome in order to increase the international participation of Japanese researchers in ...

An infrared image synthesis model
Proceedings Pacific Graphics '98. Sixth Pacific Conference on Computer Graphics and Applications (Cat. No.98EX208), 2002The paper proposes an infrared image synthesis model based on infrared physics and heat transfer. The model successfully reproduces the infrared images of the object under different viewing, ambient and internal conditions. Experimental examples illustrate the potential of our method.

Infrared upconversion hyperspectral imaging
Optics Letters, 2015In this Letter, hyperspectral imaging in the mid-IR spectral region is demonstrated based on nonlinear frequency upconversion and subsequent imaging using a standard Si-based CCD camera. A series of upconverted images are acquired with different phase match conditions for the nonlinear frequency conversion process.

Breast segmentation in infrared images
2012 20th Signal Processing and Communications Applications Conference (SIU), 2012Breast cancer detection with infrared imaging is a technique that is hazardous radiation free, increases the early detection chance and has a high detection probability. Asymmetry analysis is used for the diagnosis and the analysis is done using the breast segments obtained from the infrared image.

Infrared thermal imaging in medicine
Physiological Measurement, 2012This review describes the features of modern infrared imaging technology and the standardization protocols for thermal imaging in medicine. The technique essentially uses naturally emitted infrared radiation from the skin surface. Recent studies have investigated the influence of equipment and the methods of image recording.

Retinex enhancement of infrared images
2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008With the ability of imaging the temperature distribution of body, infrared imaging is promising in diagnostication and prognostication of diseases. However the poor quality of the raw original infrared images prevented applications and one of the essential problems is the low contrast appearance of the imagined object.

Image resolution in infrared thermography
Physics in Medicine & Biology, 1972The rise of apparent temperature in the thermograph as the detector is scanned across a temperature discontinuity is shown to be approximately exponential and to depend on the time constant of the circuit, the rate of scanning and the field size. The implication for clinical thermography is that the rise in temperature over a narrow region will be ...
