Figure 6.

Histogram comparison of segmented regions. The normalized histograms for four different segmented regions ${\gamma }_j^n$, for a particular GC and slice n using four different input parameter values ${\lambda }_t$ are shown. Inset, j-th GC and slice n displaying the corresponding different segmentations. The objective function $\mathcal{L}$ tries to minimize the difference between histograms, while at the same time maximize the areas on different image slices.
