set_descriptor_model_originT_set_descriptor_model_originSetDescriptorModelOriginSetDescriptorModelOriginset_descriptor_model_origin — Sets the origin of a descriptor model.
Signature
Herror T_set_descriptor_model_origin(const Htuple ModelID, const Htuple Row, const Htuple Column)
def set_descriptor_model_origin(model_id: HHandle, row: Union[float, int], column: Union[float, int]) -> None
Description
The operator set_descriptor_model_originset_descriptor_model_originSetDescriptorModelOriginSetDescriptorModelOriginset_descriptor_model_origin sets the origin (reference
point) of the descriptor model ModelIDModelIDModelIDmodelIDmodel_id to a new
value. The origin is specified relative to the center of gravity of the
domain (region) of the image that was used to create the descriptor model
with create_uncalib_descriptor_modelcreate_uncalib_descriptor_modelCreateUncalibDescriptorModelCreateUncalibDescriptorModelcreate_uncalib_descriptor_model, or
create_calib_descriptor_modelcreate_calib_descriptor_modelCreateCalibDescriptorModelCreateCalibDescriptorModelcreate_calib_descriptor_model. Hence, an origin of (0,0) means
that the center of gravity of the domain of the model image is used as
the origin. An origin of (-20,-40) means that the origin lies to the
upper left of the center of gravity. The new setting affects the
succeeding find_uncalib_descriptor_modelfind_uncalib_descriptor_modelFindUncalibDescriptorModelFindUncalibDescriptorModelfind_uncalib_descriptor_model and
find_calib_descriptor_modelfind_calib_descriptor_modelFindCalibDescriptorModelFindCalibDescriptorModelfind_calib_descriptor_model calls.
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 modifies the state of the following input parameter:
During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.
