bento.tl.opening

bento.tl.opening(sdata, shape_key, proportion, recompute=False) → None

Compute morphological opening of each shape.

The opening operation erodes the shape by distance d and then dilates by d, where d = proportion * shape radius.

Parameters:

• sdata (SpatialData) – Input SpatialData object

• shape_key (str) – Key in sdata.shapes containing shape geometries

• proportion (float) – Fraction of shape radius to use as opening distance

• recompute (bool, default False) – Whether to force recomputation if feature exists

Returns:

Updates sdata.shapes[shape_key] with: - ‘{shape_key}_open_{proportion}_shape’: Opened shape geometries

Return type:

None
