Visualising the results of the application of the algorithm. The heterogeneity contribution for one plane (k) would be calculated as \( H(k)={\displaystyle \sum_1^m\left(\frac{\left|{I}_p-{\overline{I}}_k\right|+\left|{I}_q-{\overline{I}}_k\right|}{2}/ \max\;\left(\frac{\left|{I}_p-{\overline{I}}_k\right|+\left|{I}_q-{\overline{I}}_k\right|\;}{2}\right)\cdot \frac{1}{d_{pq}}\right)} \)
