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

Figure 5

Tumor segmentation using the proposed method DRLS with two different initializations. (a)–(d) Adjacent slice examples—small initialization (6 pixels radius); (e)–(h) large initialization (20 pixels radius). Cyan: initial contour; green: manual radiologists’ annotation; yellow: our final segmentation by DRLS.
