Abstract EN
This study investigates a novel classification method for 3D multimodal MRI glioblastomas tumor characterization.
We formulate our segmentation problem as a linear mixture model (LMM).
Thus, we provide a nonnegative matrix M from every MRI slice in every segmentation process’ step.
This matrix will be used as an input for the first segmentation process to extract the edema region from T2 and FLAIR modalities.
After that, in the rest of segmentation processes, we extract the edema region from T1c modality, generate the matrix M, and segment the necrosis, the enhanced tumor, and the nonenhanced tumor regions.
In the segmentation process, we apply a rank-two NMF clustering.
We have executed our tumor characterization method on BraTS 2015 challenge dataset.
Quantitative and qualitative evaluations over the publicly training and testing dataset from the MICCAI 2015 multimodal brain segmentation challenge (BraTS 2015) attested that the proposed algorithm could yield a competitive performance for brain glioblastomas characterization (necrosis, tumor core, and edema) among several competing methods.
