Figure 2 Workflow for the labelling and extraction of the
training and evaluation spectra of the different classes. The first row
shows the optical images of the FL (a), DLBCL (b and c), and normal
control (e). The second row shows the labelled regions. The coloured
labels correspond to FL (grey), DLBCL, non-GCB subtype (orange), DLBCL,
GCB subtype (pink), and rLNs (green = follicle centre (FC); blue =
mantle zone (MZ)). The right column shows a selection of spectra, with
the type corresponding to the coloured bar on the left.
Table 1 shows the type of disease, label colour as manually
assigned (see figure 2), and the number of spectra obtained for
analysis.
