apply_distance_transform_xldT_apply_distance_transform_xldApplyDistanceTransformXldApplyDistanceTransformXld (Operator)
Name
apply_distance_transform_xldT_apply_distance_transform_xldApplyDistanceTransformXldApplyDistanceTransformXld
— Determine the pointwise distance of two contours using an XLD distance
transform.
Signature
Description
The operator apply_distance_transform_xldapply_distance_transform_xldApplyDistanceTransformXldApplyDistanceTransformXldApplyDistanceTransformXld
determines for
each point in ContourContourContourContourcontour
the minimal distance to the reference contour
using its XLD distance transform DistanceTransformIDDistanceTransformIDDistanceTransformIDDistanceTransformIDdistanceTransformID
.
The returned contour ContourOutContourOutContourOutContourOutcontourOut
consists of
ContourContourContourContourcontour
with the attribute 'distance'"distance""distance""distance""distance" containing the
calculated distances. They can be accessed by querying the attribute
'distance'"distance""distance""distance""distance" with get_contour_attrib_xldget_contour_attrib_xldGetContourAttribXldGetContourAttribXldGetContourAttribXld
. See the operator
reference of get_contour_attrib_xldget_contour_attrib_xldGetContourAttribXldGetContourAttribXldGetContourAttribXld
for further information about
contour attributes.
Note that the distances depend on the parameters of
create_distance_transform_xldcreate_distance_transform_xldCreateDistanceTransformXldCreateDistanceTransformXldCreateDistanceTransformXld
:
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" or 'point_to_segment'"point_to_segment""point_to_segment""point_to_segment""point_to_segment".
For further details please refer to the documentation of
create_distance_transform_xldcreate_distance_transform_xldCreateDistanceTransformXldCreateDistanceTransformXldCreateDistanceTransformXld

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
ContourContourContourContourcontour
(input_object) xld_cont(-array) →
objectHXLDContHXLDContHobject
Contour(s) for whose points the distances are
calculated.
DistanceTransformIDDistanceTransformIDDistanceTransformIDDistanceTransformIDdistanceTransformID
(input_control) xld_dist_trans →
HXLDDistTrans, HTupleHTupleHtuple (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.
