Hyperspectral imaging - Wikipedia
In the food processing industry, hyperspectral imaging, combined with intelligent software, enables digital sorters (also called optical sorters) to identify and remove defects and foreign material (FM) that are invisible to traditional camera and laser sorters.
Video-rate hyperspectral camera based on a CMOS-compatible …
2023年1月23日 · Here we develop a video-rate HS camera capable of collecting spectral information on real-world scenes with sensitivities and spatial resolutions comparable with those of a typical RGB camera.
What is hyperspectral Imaging?: A Comprehensive Guide
Hyperspectral imaging involves using an imaging spectrometer, also called a hyperspectral camera, to collect spectral information. A hyperspectral camera captures a scene’s light, separated into its individual wavelengths or spectral bands.

2024年2月17日 · High resolution hyperspectral video imaging has become highly desirable in many applications for studying dynamic optical phenomena with complicated spectral information both in microscopic and...
Hyperspectral imaging and its applications: A review
2024年6月30日 · Hyperspectral imaging is a technique that facilitates the spectrum acquisition in an image for every pixel value. HSI sensors (spectrometers imaging) usually capture near-infrared, visible, and short-wavelength infrared spectra in the range of 0.4–2.5 μm region.
Towards Ultra High-Speed Hyperspectral Imaging by Integrating ...
2024年10月14日 · Hyperspectral cameras capture HSIs with tens of spectral bands but can only be used in static scenes due to the scanning imaging mechanism (James, 2009). On the contrary, high-speed cameras can capture grayscale videos at more than \(10^4\) frames per second (FPS) (Kleinfelder et al., 2001 ; Etoh et al., 2003 ), while no spectral information ...
Hyperspectral and Multispectral Imaging | Features | Apr 2020 ...
Hyperspectral imaging is an advanced imaging technique that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging systems that record only a few spectral bands (such as red, green, and blue in visible light), hyperspectral imaging collects data in numerous contiguous bands, covering a wide range ...
Equivariant Imaging for Self-supervised Hyperspectral Image …
Abstract: Hyperspectral imaging (HSI) is a key technology for earth observation, surveillance, medical imaging and diagnostics, astronomy and space exploration. The conventional technology for HSI in remote sensing applications is based on the push-broom scanning approach in which the camera records the spectral image of a stripe of the scene at a time, while the image is …
