IET Image Processing, Volume 19, Issue 1, January/December 2025.A novel automatic segmentation method is proposed for improving the spatial consistency of scattered multiple sclerosis (MS) lesions in variant appearances. Incorporating spatial correlation learning and global context learning across different image features can further improve the spatial distinction of MS lesions in MRI and help us to classify their
