Figure 9
Results of Euclidean measure, applied to a stack of images of Chernozem soil taken with the STXM at BESSY II. The spectra of the first five clusters are shown. The first cluster contains the spectral signature of potassium edges, the second cluster represents the averaged sample, while organic components can be identified in the third cluster. The fourth cluster looks similar to the third, but the inorganic component is more present. The fifth cluster represents noise. |
