Macenko

class Macenko(StainNormalizerBase)

Constructor

Macenko(
    device: str | torch.device | None = None,
    backend: str | None = None
)

Parameters: - device: Device to use. Default: None (auto-detect) - backend: Backend ("pytorch" or "cuda"). Default: None (auto-select)

Methods

• fit(reference_images) - Compute stain matrix and target max concentration
• transform(images) - Apply Macenko normalization

Example

from stainx import Macenko

normalizer = Macenko(device="cuda")
normalizer.fit(reference)
normalized = normalizer.transform(images)
