Edge Constraint and Location Mapping for Liver Tumor Segmentation from Nonenhanced Images

Figure 8

Comparison of segmentation masks is generated by different methods. (a–d) Are the segmentation results of the other four methods; (e) is the segmentation results of our model; (g) shows the nonenhanced images and tumor details. We mark the ground truth with a red box, and the segmentation results with inaccurate positioning or poor effect are marked with a blue box.
