Title: A METHOD TO REMOVE THE SPECTRAL COMPONENTS OF ILLUMINATION AND BACKGROUND FROM MULTI-SPECTRAL AND HYPER-SPECTRAL IMAGES
Abstract:
The present invention is a method of removing the illumination and background spectral components thus isolating spectra from multi-spectral and hyper-spectral data cubes. The invention accomplishes this by first balancing a reference and sample data cubes for each spectra associated with each location, or pixel/voxel, in the spatial image. The set of residual spectra produced in the balancing step is used to obtain and correct a new set of reference spectra that is used to remove the illumination and background components in a sample data cube.
