An unsupervised pipeline that uses CLIP to label slices, CAM to localize tumors, SAM to generate pseudo-masks, and self-training with similarity filtering reaches 85.6% Dice on BraTS2020 whole-tumor segmentation.
Dataset and Implementation We evaluated our method on the BraTS2020 that comprises 369 cases each containing 3D volumes in four modalities

CLISC: Bridging clip and sam by enhanced cam for unsupervised brain tumor segmentation
An unsupervised pipeline that uses CLIP to label slices, CAM to localize tumors, SAM to generate pseudo-masks, and self-training with similarity filtering reaches 85.6% Dice on BraTS2020 whole-tumor segmentation.
