Discontinuity-preserving vector smoothing on multivariate MR images via vector mean-field annealing

One impcrtant potential ci Magnetic Resonance Imaging as comjxrcd to other medical imaging modalities is that MRI can produce well-registered multivariate images. By channg operational parameters, MRI can generate different images which emphasizes one or more tissue parameters, while maintaining reasonable registration among these images. Curremly, these multivariate ünages are ocessed or viewed individually. This jiocessing seheme is inconvenient and sometimes gives incurate results. By treating multivariate images as vector-valued images, we can process them as a whole. For quantitative analysis of medical hnages, thscontinnity-preserving or -enhancing smoothing technique becomes important In this mper, a discontinuity-preserving vector smoothing technique is intrOdUced, which is based on current scalar Mean Field Annealing.
