Segmentation of Hyperacute Cerebral Infarcts Based on Sparse Representation of Diffusion Weighted Imaging

One axial slice with complex image properties. DWI (a), ADC (b), DWI + (DWI-ADC) (c), ground truth (d), and segmented infarcts by the proposed method (e). FCM, FCM_ROI, DM, and DM_ROI methods fail to segment infarcts at this axial slice.
