get_descriptor_model_originT_get_descriptor_model_originGetDescriptorModelOriginGetDescriptorModelOriginget_descriptor_model_origin (Operator)
Name
get_descriptor_model_originT_get_descriptor_model_originGetDescriptorModelOriginGetDescriptorModelOriginget_descriptor_model_origin — Return the origin of a descriptor model.
Signature
Herror T_get_descriptor_model_origin(const Htuple ModelID, Htuple* Row, Htuple* Column)
def get_descriptor_model_origin(model_id: HHandle) -> Tuple[Union[float, int], Union[float, int]]
Description
The operator get_descriptor_model_originget_descriptor_model_originGetDescriptorModelOriginGetDescriptorModelOriginget_descriptor_model_origin returns the origin
(reference point) of the descriptor model ModelIDModelIDModelIDmodelIDmodel_id.
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.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
