MedCore: Boundary-Preserving Medical Core Pruning for MedSAM

Researchers introduced MedCore, a structured pruning framework for MedSAM that uses dual-intervention scoring and boundary-aware Fisher estimation.

On polyp segmentation benchmarks, MedCore cut parameters and FLOPs substantially while keeping Dice and boundary metrics strong.

The study argues that high Dice alone can miss boundary degradation, making boundary preservation essential for medical segmentation compression.
