2021年10月13日 · Hyperspectral imaging (HSI) is a newly developing technique combining the advantages of optical imaging and spectroscopy to simultaneously collect spatial and spectral information from a scene. A set of monochromatic images at almost continuous hundreds of wavelengths can be acquired by HSI.

Multispectral imaging combines two to five spectral imaging bands of relatively large bandwidth into a single optical system. A multispectral system usually provides a combination of visible (0.4 to 0.7 µm), near infrared (NIR; 0.7 to 1 µm), short-wave infrared (SWIR; 1 to 1.7 µm), mid-wave infrared (MWIR; 3.5 to 5 µm) or long-wave infrared ...

Multispectral imaging is a technique that involves capturing and analyzing images at multiple discrete spectral bands within the electromagnetic spectrum. Unlike hyperspectral imaging, which acquires data across a continuous range of wavelengths, multispectral imaging is characterized by capturing information at several specific, predefined bands.

2024年4月3日 · Multispectral imaging is a technique that captures light across a broad range of spectral bands, extending beyond what the human eye can see, including infrared and ultraviolet light. This approach significantly surpasses traditional color imaging by revealing details invisible to the naked eye.

Multispectral imaging (MSI) is a unique layer-by-layer imaging technique that allows the visualization of a wide array of retinal and choroidal pathologies including retinovascular disorders, retinal pigment epithelial changes, and choroidal lesions.

A multispectral imaging (MSI) system is similar to one that is hyperspectral but does have key differences. In comparison to the effectively continuous wavelength data collection of an HSI, an MSI concentrates on several preselected wavebands based on the application at hand.

Hyperspectral imaging (HSI) and multispectral imaging (MSI) are two related technologies that make use of specialized vision systems to acquire extra image information from extended regions of the electromagnetic spectrum aside from the visible spectrum (Figure 1).

Multispectral imaging takes the detection capability of machine vision beyond just color inspection. With wafer-level coating of multispectral filters, advanced multispectral cameras now can be designed in a compact form factor.

Multispectral cameras are highly specialized industrial imaging devices that see much more than "just" color. They measure image data in specific wavelength ranges of the electromagnetic spectrum, far beyond what the human eye can see (380-780 nanometers).

In this paper, we present an efficient and robust approach for recovering spectral reflectance in a scene that combines the advantages of using multiple spectral sources and a multispectral camera.
