L2R-OASIS
The Open Access Series of Imaging Studies (OASIS) is a project aimed at providing the scientific community with free access to neuroimaging datasets for the purpose of advancing discoveries in basic and clinical neuroscience. There are four versions available on the OASIS official website, and this description refers to the OASIS dataset version used in the L2R Challenge (Medical Image Registration in MELBA). This dataset is used for segmentation and registration and contains a total of 416 3D M
