eye_ibug_open_38_to_eye_ibug_open_38

menpo.landmark.eye_ibug_open_38_to_eye_ibug_open_38(pcloud)

Apply the IBUG 38-point open eye semantic labels.

The semantic labels applied are as follows:

• upper_eyelid

• lower_eyelid

• iris

• pupil

• sclera

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