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 ...

A perspective on medical infrared imaging
Journal of Medical Engineering & Technology, 2005Since the early days of thermography in the 1950s, image processing techniques, sensitivity of thermal sensors and spatial resolution have progressed greatly, holding out fresh promise for infrared (IR) imaging techniques. Applications in civil, industrial and healthcare fields are thus reaching a high level of technical performance.

Learning to Colorize Infrared Images
2018This paper focuses on near infrared (NIR) image colorization by using a Generative Adversarial Network (GAN) architecture model. The proposed architecture consists of two stages. Firstly, it learns to colorize the given input, resulting in a RGB image.

Infrared Imaging of Brain Function
1993The aim of this article is to describe in detail a technique to record the thermal response of the animal brain cortex using an infrared (IR) optical system (Budko et al., 1985). We compare this method, which we call thermoencephaloscopy (TES), with other techniques for studying the cortex. Results obtained using TES are analyzed in relation to results
