A Unified Level Set Framework Combining Hybrid Algorithms for Liver and Liver Tumor Segmentation in CT Images

Figure 3

The comparison between region-growing for original CT image and region-growing for binary image. (a)-(b) indicate the original image M, (e)-(f) indicate the binary image of image M, (g)-(j) indicate the original CT image N, and (k)-(l) denote the binary image of image N. And images below (a)-(l) denote the corresponding results of region-growing. The initial seed points are denoted by red points, and values of (a)-(d) were set to 0.04, 0.05, 0.06, and 0.07, respectively. values of (g)-(j) were all set to 0.08, values of (e) and (k) were both set to 0.3, and values of (f) and (l) were both set to 0.8.
