Defaults to ``False``. distance_metric: : [``"euclidean"``, ``"chessboard"``, ``"taxicab"``] the metric used to compute surface distance. Defaults to ``"euclidean"``. percentile: an optional float number between 0 and 100. If specified, the corresponding percentile of the Hausdorff Distance rather than the maximum result will be achieved. Defaults to ``None``. directed: whether to calculate directed Hausdorff distance. Defaults to ``False``. reduction: define the mode to reduce metrics, will only execute reduction on `not-nan` values, available reduction modes: {``"none"``, ``"mean"``, ``"sum"``, ``"mean_batch"``, ``"sum_batch"``, ``"mean_channel"``, ``"sum_channel"``}, default to ``"mean"``. if "none", will not do reduction. output_transform: callable to extract `y_pred` and `y` from `ignite.engine.state.output` then construct `(y_pred, y)` pair, where `y_pred` and `y` can be `batch-first` Tensors or lists of `channel-first` Tensors. the form of `(y_pred, y)` is required by the `update()`. `engine.state` and `output_transform` inherit from the ignite concept: https://pytorch.org/ignite/concepts.html#state, explanation and usage example are in the tutorial: https://github.com/Project-MONAI/tutorials/blob/master/modules/batch_output_transform.ipynb. save_details: whether to save metric computation details per image, for example: hausdorff distance of every image. default to True, will save to `engine.state.metric_details` dict with the metric name as key. )r rrrr) metric_fnrrN)rsuper__init__) selfr rrrrrrr __class__r r rs"zHausdorffDistance.__init__)r rrrrrrrrrrrrrrr)__name__ __module__ __qualname____doc__rMEANr __classcell__r r rr rsrN) __future__rcollections.abcrmonai.handlers.ignite_metricr monai.metricsr monai.utilsrrr r r r s
