Comparison of the segmentation results of the pathological tissue regions obtained for a GBM patient using the different NMF methodologies. The left figure of each row shows the obtained segmentation for active tumor (purple), necrosis (red) and edema (yellow). The second to fourth figure of each row show the individual segmentation for active tumor, necrosis and edema, respectively. The top row shows manual segmentation, whereas the other rows show the overlap between the NMF (blue) and manual (green) segmentation result. Segmentation overlap is marked in cyan
