DermNet, a multi-resolution class-incremental SegFormer teacher–student framework, achieves Dice scores at 10x magnification of 0.95 (epidermis) through 0.98 (hypodermis) on 290 skin WSI slides.
- Why it matters: Skin-layer segmentation in histopathology needs to handle heterogeneous morphology and multiple magnifications, while avoiding catastrophic forgetting when learning additional tissue classes.
- What they did: DermNet progressively trains on WSIs at 10x, 5x, and 2x using exemplar replay, mutual knowledge and distillation, Kullback-Leibler and boundary losses, plus Elastic Weight Consolidation.
- The result: It outperforms U-Net and alternative SegFormer strategies at all magnifications, and on an independent dataset yields Dice scores from 0.89 to 0.97 across classes, supporting cross-dataset generalizability.
