Figure 5

Drusen detection algorithm example. This figure presents a test image containing two drusen (a). In images (b and c) the gradient vectors and the pixels search directions are shown. Image (d) presents the initial label propagation in the two first upper rows and the label propagation paths. The labels equivalence table shown in figure (e) was built from the label propagation procedure and was applied to figure (d) in order to obtain the final labels image (f). In this example the two drusen are correctly segmented and their maximum point is highlighted.
