2014 Human Vision and Electronic Imaging XIX  
We recently presented a color transform that produces fused nighttime imagery with a realistic color appearance (Hogervorst & Toet, 2010, Information Fusion, 11-2, 69-77).  ...  In some cases, color remapping II imagery and fusion with IR imagery restored the fixation order of these image details.  ...  information from grayscale nighttime imagery than from either colorized multispectral imagery or daytime photographs.  ...

2021 arXiv   pre-print
To the best of our knowledge, our detector achieves the best single-modality detection results on KAIST with respect to the state-of-the-art.  ...  Our model, based on the Least-Squares Generative Adversarial Network, is trained to synthesize realistic thermal versions of input RGB images which are then used to augment the limited amount of labeled  ...  We first describe the dataset and evaluation metrics used, then in Section IV-B give a qualitative evaluation of the performance of our GAN in generating thermal imagery from RGB input.  ...

Improved Color Mapping Methods for Multiband Nighttime Image Fusion

2017 Journal of Imaging  
Previously, we presented two color mapping methods for the application of daytime colors to fused nighttime (e.g., intensified and longwave infrared or thermal (LWIR)) imagery.  ...  These mappings not only impart a natural daylight color appearance to multiband nighttime images but also enhance their contrast and the visibility of otherwise obscured details.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...

Image fusion for tactical applications

1998 Infrared Technology and Applications XXIV  
Just as in satellite imagery of the earth, multispectral data is required in order to extract the maximum amount of information from a scene.  ...  Imagery from various sensors must be calibrated, enhanced and spatially registered in order to achieve the desired "fusion" of information into a single "picture" for rapid assessment.  ...  Both the infrared and fused color sensor formats provide enough essential features to allow an observer to perceptually organize a complex nighttime scene.  ...
