Figure 11.28a and b show two intensity profiles (marked with the red curve) of the
sub-RPE region (Fig. 11.26a) in the GA and the normal regions, respectively. This
principle constitutes the basic idea of the proposed RSAP technique. The flowchart
of our technique is shown in Fig. 11.27, which comprises the following operations,
