Figure 12.5
Four independent base images of the psoriasis ensemble. By analogy to the PCA
eigenimages, these base images are considered the underlying images of the
recorded fluorescence images as clarified by the image synthesis model shown in
figure 12.4. However, note that none of the independent base images shows large
structures like the first PCA eigenimages in figure 12.3.
for the linear combinations of the independent source images
Y
that
comprise the original fluorescence images
X
have to be determined next.
Therefore, consider that instead of the original fluorescence images
X
,
their corresponding eigenimages
U
are used to train the network, and
hence
W
I
U
=
Y
.
