Qualitative results of segmentation on our collected dataset. (a) shows examples of segmentations from BL-net and refinement strategies. (b) shows the refinement process of a bad case’s detected boundaries and segmented layers. U-net and S-net are two baseline models, bi-decision is proposed to refine outputs of the l-part of BL-net, interpolation is proposed to refine outputs of the b-part of BL-net and combination strategy is to fuse the two refined results. Refinement strategies correct topology error of bad segmentations.
