Fig. 15 Embedding the shape model to the image domain and the final segmentation. (i)ACT
data after the extraction of spinal cord. (ii) Shape model initialization (the blue color show the
outer surface of the variability region J). The contour J is placed equally in every slice using the
obtained ROI. (iii) Embedding the shape model to the image domain. (iv) Final segmentation using
three models: The intensity, spatial interaction, and shape information. Images and results are
shown in the (a) sagittal, (b) coronal, and (c) axial views
