Webb30 maj 2024 · Hyperspectral Image Analysis Tools. When I was first introduced to image analysis by Paul Geladi he referred to it as Multivariate Image Analysis or MIA. So when we released our image analysis package back in 2005 we called it MIA_Toolbox. Since then more and more analytical techniques have been adapted to produce images. Figuratively speaking, hyperspectral sensors collect information as a set of 'images'. Each image represents a narrow wavelength range of the electromagnetic spectrum, also known as a spectral band. These 'images' are combined to form a three-dimensional (x,y,λ) hyperspectral data cube for processing and analysis, where x and y represent two spatial dimensions of the scene, and λ represents the spectral dimension (comprising a range of wavelengths). 食べ物 うんちになるまで 時間
