Weakly-Supervised teacher-Student network for liver tumor segmentation from non-enhanced images
Medical Image Analysis(2021)
摘要
•Contrast-free liver tumor segmentation by weakly-supervised teacher-student network.•Dual-strategy DRL is proposed for accurate tumor detection.•Uncertainty-Sifting Self-Ensembling is proposed to predict the tumor mask accurately.
