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.
