Dynamic Regulation of Level Set Parameters Using 3D Convolutional Neural Network for Liver Tumor Segmentation

Figure 8

3D liver tumor segmentation using DRLS and FLS in comparison. (a)–(d), (e)–(h), and (i)–(l) are adjacent slices of three 3D CT scans. (a)–(d) are located inside the tumor, and the other two are close to or outside the tumor boundary. Cyan: initial contour; green: manual radiologists’ annotation; red: FLS result; yellow: our proposed method.
