Sensors, 2022 SWIR imaging bears considerable advantages over visible-light (color) and thermal images in certain challenging propagation conditions. Thus, the SWIR imaging channel is frequently used in multi-spectral imaging systems (MSIS) for long-range surveillance

Use of the Cross-Spectral Density Matrix for Enhanced Passive Ultrasound Imaging of Cavitation [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2021 Passive ultrasound imaging is of great interest for cavitation monitoring. Spatiotemporal monitoring of cavitation bubbles in therapeutic applications is possible using an ultrasound imaging probe to passively receive the acoustic signals from the bubbles.

A hyperspectral imaging framework integrating band selection and deep learning for beverage stain classification in forensic analysis [PDF]
Scientific ReportsThe technique of Hyperspectral Imaging (HSI) is significant in the field of non-destructive forensic crime scene investigation, as it allows for the identification of minor spectral changes over a broad range of wavelengths.

Understanding Photon-Counting CT: Physics, Detector Technology, and Image Reconstructions [PDF]
SensorsPhoton-counting computed tomography (PCCT) represents a detector-level transformation in CT imaging. Unlike conventional energy-integrating detectors, photon-counting detectors directly convert individual X-ray interactions into electrical pulses and ...

Cross-spectral fusion of thermal and RGB imaging for objective pain estimation.
PLOS Digital HealthPain assessment remains challenging for patients unable to verbally communicate, including neonates, cognitively impaired individuals, sedated patients, and those who suppress expressions due to cultural norms or stoicism. We demonstrate that integrating

Spectral scaling transformations of nonstationary light [PDF]
EPJ Web of Conferences, 2022 We present optical systems, which transform isodiffracting nonstationary beams into fields obeying either cross-spectral purity or spectral invariance. The designs are hybrid refractive-diffractive imaging systems, which are able to perform the desired ...

Balancing Heterogeneous Image Quality for Improved Cross-Spectral Face Recognition [PDF]
Sensors, 2021 Matching infrared (IR) facial probes against a gallery of visible light faces remains a challenge, especially when combined with cross-distance due to deteriorated quality of the IR data. In this paper, we study the scenario where visible light faces are acquired at a short standoff, while IR faces are long-range data.

SkImager: a concept device for in-vivo skin assessment by multimodal imaging; pp. 301–308 [PDF]
Proceedings of the Estonian Academy of Sciences, 2014 A compact prototype device for diagnostic imaging of skin has been developed and tested. Polarized LED light at several spectral regions is used for illumination, and round skin spot of diameter 34Â mm or 11Â mm is imaged by a CMOS sensor via cross ...
