menpo.landmark.eye_ibug_open_38_to_eye_ibug_open_38_trimesh(x, return_mapping=False)

Apply the IBUG 38-point open eye semantic labels, with trimesh connectivity.

The semantic labels applied are as follows:

• tri

Parameters:

• x (LabelledPointUndirectedGraph or PointCloud or ndarray) – The input labelled point graph, pointcloud, subclass of those or array to label. If a pointcloud is passed, then only the connectivity information is propagated to the pointcloud (a subclass of PointCloud may be returned).
• return_mapping (bool, optional) – Only applicable if a PointCloud or ndarray is passed. Returns the mapping dictionary which maps labels to indices into the resulting PointCloud (which is then used to for building a LabelledPointUndirectedGraph. This parameter is only provided for internal use so that other labellers can piggyback off one another.

Returns:

• x_labelled (LabelledPointUndirectedGraph or PointCloud) – If a LabelledPointUndirectedGraph was passed, a LabelledPointUndirectedGraph is returned. This labelled pointgraph will contain specific labels and these labels may refer to sub-pointclouds with specific connectivity information.

  If a PointCloud was passed, a PointCloud is returned. Only the connectivity information is propagated to the pointcloud (a subclass of PointCloud may be returned).

• mapping_dict (ordereddict {str -> int ndarray}, optional) – Only returned if return_mapping==True. Used for building LabelledPointUndirectedGraph.

Raises:

: :map:`LabellingError` – If the given labelled point graph/pointcloud contains less than the expected number of points.
