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.

Visible/Infrared Imaging on the Rise [In the Spotlight]
IEEE Signal Processing Magazine, 2013The news media recently showed how infrared imagery aided the authorities in capturing the second Boston Marathon bomber suspect, now a significant tool in the public safety arsenal [1]. It also clearly illustrates the progress in infrared hardware technology since Desert Storm in 1991. The images shown were less grainy (noisy) and had more gray scales,

Conversion of Infrared Images to Visible in Color
Applied Optics, 1968An ir line scan instrument has been developed that scans a scene simultaneously with three separate spectral regions and produces an image of the scene as a color photograph. The three spectral regions are 0.5-1.0 micro, 3.0-5.5 micro and 8.0-14.0 micro. The ir detectors used are Si, InSb, and Ge:Hg, respectively.

Effective method for fusing infrared and visible images
Journal of Electronic Imaging, 2021Recently, deep learning has become a rapidly developing tool in the field of image fusion. An innovative image fusion method for fusing infrared images and visible-light images is proposed. The backbone network is an autoencoder. Different from previous autoencoders, the information extraction capability of the encoder is enhanced, and the ability to ...

Iterative Method for Fusion of Infrared and Visible Images
2018 9th International Symposium on Telecommunications (IST), 2018This paper proposes a novel fusion method for visible and infrared images. The infrared and visible samples are obtained by a sampling pattern such as star and spiral. Then, the samples are fused according to fusion rules. Finally, the proposed method is applied to fuse the infrared and visible samples.

Fusion of Infrared and Visible Images for Face Recognition
2004A number of studies have demonstrated that infrared (IR) imagery offers a promising alternative to visible imagery due to it’s insensitive to variations in face appearance caused by illumination changes. IR, however, has other limitations including that it is opaque to glass.

Multispectral visible and infrared imaging for face recognition
2008 IEEE Computer Society Conference on Computer Vision and Pattern Recognition Workshops, 2008Multispectral imaging in the visible and near infrared spectra helps reduce color variations in the face due to changes in illumination source types and directions. Thermal infrared imaging provides useful signatures of the face that is insensitive to ambient lighting through the measurement of heat energy radiated from the object.

A comparative study on fusion of visible and infrared images
2018 26th Signal Processing and Communications Applications Conference (SIU), 2018In this paper, principal component analysis (PCA), laplacian pyramid (LP), discrete wavelet transform (DWT), non-subsampled contourlet transform (NSCT), Bayesian PCA (BPCA), and non-negative matrix factorization (NMF) methods are compared in order to obtain a single informative image from visible and thermal images.

Photosensitive element for an infrared-to-visible image converter
Applied Optics, 1995We show that gels can be used to record images formed by IR radiation (in the 10.6-µm wavelength) and then be played back in the visible by a dark-background-illumination technique. The recording process is transient.
