Application of hierarchical multi-phase C-V method based on narrow band to MRI image segmentation
MRI图像的基于窄带的递进多分区C-V分割方法

A hierarchical multi-phase C-V method based on narrow band was proposed. Several stages are involved in the proposed method, and each stage needs just one level set. Besides, in every segmentation stage only the points of narrow band need to be dealt with. Therefore, the computation work has been greatly reduced compared with the multi-phase C-V method. 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.
