An Automatic Random Walker Algorithm for Segmentation of Ground Glass Opacity Pulmonary Nodules

Figure 7

Comparison of segmentation results between improved random walker with the acquired nodule seeds and improved random walker without the acquired nodule seeds. (a) The background seeds by a local search strategy. (b) The segmentation result by the improved random walker without the acquired nodule seeds. (c) The segmentation result of the improved random walker with the acquired nodule seeds.
