Researchers have developed a novel shape-based approach for glioma grading using tumor contours, outperforming traditional pixel-based methods. This method, which aligns closed contours and separates global deformation from residual Fourier shape, achieved a mean balanced accuracy of 71.5% on the BraTS 2020 dataset. The selected multilayer perceptron (MLP) models used significantly fewer parameters than pixel baselines, demonstrating improved interpretability and scalability. AI
