Brain Tumor Classification Using AFM in Combination with Data Mining Techniques
Figure 8
The resulting mean value (solid line) of the Minkowski functional Euler-characteristic and the 1σ confidence intervals (dashed lines) for astrocytoma (red) and glioblastoma multiforme (green). Both types of tumors show sigmoid curves which differ in a very characteristic way. The green glioblastoma multiforme curves show an overall flat profile, and the red astrocytoma curves appear more rounded.
