Abstract interface for tissue mask providers. Defines the TissueMaskProvider abstract base class that TileExtractor depends on for obtaining binary tissue masks.

​
TissueMaskProvider

Abstract base class for tissue mask providers. Every provider must implement generate, which receives an open WSIReader and returns a 2-D uint8 binary mask where 1 = tissue. TileExtractor depends only on this interface, so any concrete provider — algorithmic, model-based, or pre-computed — can be plugged in. Example class MyCustomMask(TissueMaskProvider): def generate(self, reader): return load_from_database(reader.path)

​
generate

Generates a binary tissue mask for the given slide.
​
WSIReader
required
An open WSI reader.
​
bool
Whether to display a progress bar. Defaults to True.
​
np.ndarray
A uint8 mask of shape (H, W) with values in {0, 1} where 1 = tissue.
