Fig. 11.9 Segmentation results for small drusen with high reflectivity IS/OS layers
middle axes of the RPE layer will be convex for the drusen with high reflectivity
and a homogeneous pattern. Figure 11.9 shows two segmentation results for small
drusen. For these two images, the IS/OS layers have similar reflectivity with the RPE
layers, and the IS/OS layer is spatially close to the RPE layer. From Fig. 11.9, it can
be seen that although the RPE layer estimation (the red lines) is not very accurate due
to the confounding influence of the IS/OS layers, our algorithm can still obtain good
segmentation results. Figure 11.10 shows that even when estimation of the boundary
