Deep MRI glioma segmentation via multiple guidances and hybrid enhanced-gradient cross-entropy loss

作者:

Highlights:

• Glioma segmentation network is designed based on glioma hierarchical structure.

• Whole glioma prediction is proposed to reduce wrongly segmented points.

• Glioma boundary prediction is introduced to provide semantic glioma contour.

• Importance ranking fusion is introduced to reduce feature redundancy.

• Our hybrid enhanced-gradient cross-entropy loss can solve class-imbalance problem.
