set_descriptor_model_originT_set_descriptor_model_originSetDescriptorModelOriginSetDescriptorModelOrigin (Operator)
Name
set_descriptor_model_originT_set_descriptor_model_originSetDescriptorModelOriginSetDescriptorModelOrigin — Sets the origin of a descriptor model.
Signature
Herror T_set_descriptor_model_origin(const Htuple ModelID, const Htuple Row, const Htuple Column)
Description
The operator set_descriptor_model_originset_descriptor_model_originSetDescriptorModelOriginSetDescriptorModelOriginSetDescriptorModelOrigin sets the origin (reference
point) of the descriptor model ModelIDModelIDModelIDModelIDmodelID 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_modelCreateUncalibDescriptorModelCreateUncalibDescriptorModelCreateUncalibDescriptorModel, or
create_calib_descriptor_modelcreate_calib_descriptor_modelCreateCalibDescriptorModelCreateCalibDescriptorModelCreateCalibDescriptorModel. 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_modelFindUncalibDescriptorModelFindUncalibDescriptorModelFindUncalibDescriptorModel and
find_calib_descriptor_modelfind_calib_descriptor_modelFindCalibDescriptorModelFindCalibDescriptorModelFindCalibDescriptorModel 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.
