Abstract
An image analysis system to segment multiple sclerosis lesions of (MR) brain volumes is proposed. The method uses Markov Random Fields (MRF) both at low and high levels. The neighborhood system used in this MRF is defined in three types: (1) Voxel to voxel: a low-level heterogeneous neighborhood used to restore noisy images. (2) Voxel to segment: a fuzzy atlas is registered elastically with the MRF then used as a-priori knowledge to correct miss-classified voxels. (3) Segment to segment: Lesion candidates are processed by a feature based classifier that looks at unary and neighborhood information to eliminate false positives.
