Figure 11.15: Segmentation of the circle with a big gap (Fig. 11.12 (middle))
using ε = 1 (top), ε = 10 − 2 (middle), and ε = 10 − 5 (bottom). For bigger missing
part a smaller ε is desirable. In the left column we see how close to the edges
the isolines are accumulating and closing the gap, and in the right we see how
steep the segmentation function is along the gap (color slide).
