Description

The operator create_local_deformable_model_xldcreate_local_deformable_model_xldCreateLocalDeformableModelXldCreateLocalDeformableModelXldcreate_local_deformable_model_xld creates a deformable model used for local deformable matching from the XLD contours passed in ContoursContoursContourscontourscontours. The XLD contours represent the gray-value edges of the object to be searched for. In contrast to the operator create_local_deformable_modelcreate_local_deformable_modelCreateLocalDeformableModelCreateLocalDeformableModelcreate_local_deformable_model, which creates a deformable model from a template image, the operator create_local_deformable_model_xldcreate_local_deformable_model_xldCreateLocalDeformableModelXldCreateLocalDeformableModelXldcreate_local_deformable_model_xld creates the deformable model from XLD contours.

The center of gravity of the smallest surrounding rectangle of the ContoursContoursContourscontourscontours that is parallel to the coordinate axes is used as the origin (reference point) of the model. A different origin can be set with set_deformable_model_originset_deformable_model_originSetDeformableModelOriginSetDeformableModelOriginset_deformable_model_origin.

For further explanation on the deformable model and its parameters we refer to the description of create_planar_uncalib_deformable_modelcreate_planar_uncalib_deformable_modelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelcreate_planar_uncalib_deformable_model and create_local_deformable_modelcreate_local_deformable_modelCreateLocalDeformableModelCreateLocalDeformableModelcreate_local_deformable_model. Note that set_local_deformable_model_metricset_local_deformable_model_metricSetLocalDeformableModelMetricSetLocalDeformableModelMetricset_local_deformable_model_metric can be used to change the metric of the model.

Attention

Note that, in contrast to the operator create_local_deformable_modelcreate_local_deformable_modelCreateLocalDeformableModelCreateLocalDeformableModelcreate_local_deformable_model, it is not possible to specify a minimum size of the model components. To avoid small model components in the model, short contours can be eliminated with the operator select_contours_xldselect_contours_xldSelectContoursXldSelectContoursXldselect_contours_xld before calling create_local_deformable_model_xldcreate_local_deformable_model_xldCreateLocalDeformableModelXldCreateLocalDeformableModelXldcreate_local_deformable_model_xld.

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
