Illustration of tumor VOI extraction using confidence connected region growing. (a) Confidence connected segmentation results under l in the range [1.5, 2.5]. (b) The integrated image of (a). (c) The extracted tumor mask. (d) The bounding box of tumor region (green rectangle), the tumor mask (yellow contour), and the seed point (red point).
