Data processing for spectrum-images: extracting information from the data mountain

Several analytical methods of electron, X-ray and ion microscopy are now capable of generating images containing an entire spectrum at each pixel. These spectrum-images require new software tools for visualisation, classification and analysis. This paper outlines a new method of visualisation for spectrum-images and two image classification methods that can be used to identify the phases present in the sample. q1999 Elsevier Science B.V.
