apply_distance_transform_xldT_apply_distance_transform_xldApplyDistanceTransformXldApplyDistanceTransformXldapply_distance_transform_xld (Operator)
Name
apply_distance_transform_xldT_apply_distance_transform_xldApplyDistanceTransformXldApplyDistanceTransformXldapply_distance_transform_xld — Determine the pointwise distance of two contours using an XLD distance
transform.
Signature
Description
The operator apply_distance_transform_xldapply_distance_transform_xldApplyDistanceTransformXldApplyDistanceTransformXldApplyDistanceTransformXldapply_distance_transform_xld determines for
each point in ContourContourContourContourcontourcontour the minimal distance to the reference contour
using its XLD distance transform DistanceTransformIDDistanceTransformIDDistanceTransformIDDistanceTransformIDdistanceTransformIDdistance_transform_id.
The returned contour ContourOutContourOutContourOutContourOutcontourOutcontour_out consists of
ContourContourContourContourcontourcontour with the attribute 'distance'"distance""distance""distance""distance""distance" containing the
calculated distances. They can be accessed by querying the attribute
'distance'"distance""distance""distance""distance""distance" with get_contour_attrib_xldget_contour_attrib_xldGetContourAttribXldGetContourAttribXldGetContourAttribXldget_contour_attrib_xld. See the operator
reference of get_contour_attrib_xldget_contour_attrib_xldGetContourAttribXldGetContourAttribXldGetContourAttribXldget_contour_attrib_xld for further information about
contour attributes.
Note that the distances depend on the parameters of
create_distance_transform_xldcreate_distance_transform_xldCreateDistanceTransformXldCreateDistanceTransformXldCreateDistanceTransformXldcreate_distance_transform_xld:
The distances are clipped to the maximum distance specified by the parameter
MaxDistance. The parameter Mode determines whether the distances are
calculated 'point_to_point'"point_to_point""point_to_point""point_to_point""point_to_point""point_to_point" or 'point_to_segment'"point_to_segment""point_to_segment""point_to_segment""point_to_segment""point_to_segment".

Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters
ContourContourContourContourcontourcontour (input_object) xld_cont(-array) → objectHXLDContHObjectHXLDContHobject
Contour(s) for whose points the distances are
calculated.
DistanceTransformIDDistanceTransformIDDistanceTransformIDDistanceTransformIDdistanceTransformIDdistance_transform_id (input_control) xld_dist_trans → HXLDDistTrans, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the XLD distance transform of the
reference contour.
Result
If all parameters are correct, the operator returns the
value 2 (
H_MSG_TRUE)
. Otherwise, an exception is raised.
