Checkpoint for Multistain Pretraining for Slide Representation Learning in Pathology (ECCV'24)
Welcome to the official HuggingFace repository of the ECCV 2024 paper, "Multistain Pretraining for Slide Representation Learning in Pathology". This project was developed at the Mahmood Lab at Harvard Medical School and Brigham and Women's Hospital.

Preprocessing: tissue segmentation, patching, and patch feature extraction
We are extracting CONCH features at 10x magnification on 256x256-pixel patches. Please refer to Madeleine public implementation to extract patch embeddings from a WSI.
Extracting MADELEINE slide encoding
You can obtain and run MADELEINE slide encoding (trained on Acrobat breast samples at 10x magnification) using:
from core.models.factory import create_model_from_pretrained
model, precision = create_model_from_pretrained('./models/')
feats = load_h5('your_path_to_conch_patch_embeddings/XXX.h5')
with torch.no_grad():
with torch.amp.autocast(device_type="cuda", dtype=precision):
wsi_embed = model.encode_he(feats=feats, device='cuda')
