meddlr.metrics.ASSD

class meddlr.metrics.ASSD(connectivity: int = 1, channel_names: Optional[Sequence[str]] = None, reduction='none', compute_on_step: bool = False, dist_sync_on_step: bool = False, process_group: Optional[bool] = None, dist_sync_fn: Optional[bool] = None)

Average symmetric surface distance.

Variables

• connectivity (int) – The neighbourhood/connectivity considered when determining the surface of the binary objects.

• channel_names (Sequence[str]) – Category names corresponding to the channels.

Note

This metric is not differentiable.

Parameters

• connectivity (int) – The neighbourhood/connectivity considered when determining the surface of the binary objects. If in doubt, leave it as it is.
