Automatic Graph Cut Segmentation of Lesions in CT Using Mean Shift Superpixels
Comparison of pixel-based and superpixel-based graph cut algorithms on three different types of nodules. For each nodule in (a), (b), and (c), the first row shows the 3D nodule in the original CT subimages; the second row shows segmentation results based on the pixel-based method, and the last row shows results using the proposed superpixel based method.
