The application of hierarchical multi-phase C-V method combined with narrow band on MRI image segmentation

A hierarchical multi-phase C-V method combined with narrow band is proposed. Because the proposed method is composed of several steps, and each step needs just one level set. Besides, in every segmentation step only the points of narrow band need to be treated. So the computation has been greatly reduced compared with the multi-phase C-V method. Various experimental results of MRI (Magnetic resonance imaging) image show that the proposed method is efficient and stable. The segmentation effect and speed is improved greatly when the image has complex structure.
