Automatic Graph Cut Segmentation of Lesions in CT Using Mean Shift Superpixels

Figure 5

An example of the segmentation of a part-solid nodule based on the automatic calculation of the initialization (a) 3D nodule in three contiguous CT slices; (b) initial foreground based on high spherical concentration; (c) initial background; (d) segmentation results by the proposed graph cut based method.
