Spectral unmixing vs compensation
WebSpectral compensation is a process in which fluorescence emissions are collected holistically as spectra; compensation is performed by unmixing the spectrum of each fluorescent probe from the total signal using linear least squares to solve an over-determined system of equations.. Spectral compensation can be calculated and applied … WebDec 2, 2024 · Linear unmixing is advantageous in the way that it is well suited for resolving spectra from pixels that have a mixed contribution from different fluorophores, as it calculates the best linear fit of any combination of fluorescent spectra in an individual pixel.

WebApr 10, 2024 · Spectral unmixing (SU) of hyperspectral images (HSIs) is one of the important areas in remote sensing (RS) that needs to be carefully addressed in different RS applications. Despite the high spectral resolution of the hyperspectral data, the relatively low spatial resolution of the sensors may lead to mixture of different pure materials within the …
WebSpectral unmixing is an algorithm, which is applied to fluorescence images to correct for spectral bleedthrough between different color channels. E.g. the emission spectra of the fluorochromes CFP and YFP partially overlap, and CFP signals also appear in the YFP fluorescence channel. This overlap can be corrected by spectral unmixing.
