get_descriptor_model_originT_get_descriptor_model_originGetDescriptorModelOriginGetDescriptorModelOrigin (Operator)
Name
get_descriptor_model_originT_get_descriptor_model_originGetDescriptorModelOriginGetDescriptorModelOrigin — Return the origin of a descriptor model.
Signature
Herror T_get_descriptor_model_origin(const Htuple ModelID, Htuple* Row, Htuple* Column)
Description
The operator get_descriptor_model_originget_descriptor_model_originGetDescriptorModelOriginGetDescriptorModelOriginGetDescriptorModelOrigin returns the origin
(reference point) of the descriptor model ModelIDModelIDModelIDModelIDmodelID.
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.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
