Automatic Graph Cut Segmentation of Lesions in CT Using Mean Shift Superpixels
Figure 4
An example of the segmentation of an attached solid nodule based on the automatic calculation of the initial foreground and background. (a) 3D nodule in two contiguous CT slices; (b) initial foreground based on high spherical concentration; (c) initial background; (d) segmentation results by the proposed graph cut based method.
