Name

set_shape_model_paramT_set_shape_model_paramSetShapeModelParamSetShapeModelParamset_shape_model_param — Set selected parameters of the shape model.

Signature

Description

The operator set_shape_model_paramset_shape_model_paramSetShapeModelParamSetShapeModelParamset_shape_model_param sets the selected parameters GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name in the shape model ModelIDModelIDModelIDmodelIDmodel_id. The following parameters can be modified:

'min_contrast'"min_contrast""min_contrast""min_contrast""min_contrast"

Sets the minimum contrast of the object in the search images for the shape model ModelIDModelIDModelIDmodelIDmodel_id. Thereby, the value of 'min_contrast'"min_contrast""min_contrast""min_contrast""min_contrast" that was originally set, e.g., with create_shape_modelcreate_shape_modelCreateShapeModelCreateShapeModelcreate_shape_model, is overwritten for the shape model ModelIDModelIDModelIDmodelIDmodel_id. Note that if the shape model ModelIDModelIDModelIDmodelIDmodel_id was read from file and if this file should be changed as well, the shape model ModelIDModelIDModelIDmodelIDmodel_id must again be written to file after the execution of the operator set_shape_model_paramset_shape_model_paramSetShapeModelParamSetShapeModelParamset_shape_model_param.

'timeout'"timeout""timeout""timeout""timeout"

Sets the maximum runtime of the operators used to find the shape model ModelIDModelIDModelIDmodelIDmodel_id (e.g., find_shape_modelfind_shape_modelFindShapeModelFindShapeModelfind_shape_model). This is especially useful in cases where a maximum cycle time has to be ensured. The 'timeout'"timeout""timeout""timeout""timeout" must be given in milliseconds. The temporal accuracy depends on several factors including the size of the model, the speed of your computer, and the 'timer_mode'"timer_mode""timer_mode""timer_mode""timer_mode" set via set_systemset_systemSetSystemSetSystemset_system. Be aware that the runtime of the search increases by up to 10 percent with activated timeout. To disable the timeout you can either use a negative value or 'false'"false""false""false""false".

'border_shape_models'"border_shape_models""border_shape_models""border_shape_models""border_shape_models"

This parameter determines whether the shape model ModelIDModelIDModelIDmodelIDmodel_id to be found with, e.g., find_shape_modelfind_shape_modelFindShapeModelFindShapeModelfind_shape_model, may lie partially outside the image (i.e., whether they may cross the image border). Partially means that the model's origin still must be located within the image. A different origin set with set_shape_model_originset_shape_model_originSetShapeModelOriginSetShapeModelOriginset_shape_model_origin is not taken into account.

The value of 'border_shape_models'"border_shape_models""border_shape_models""border_shape_models""border_shape_models" can be 'true'"true""true""true""true", 'false'"false""false""false""false", or 'system'"system""system""system""system". The value 'system'"system""system""system""system" is the default behavior and uses the system-wide used value that was set by set_systemset_systemSetSystemSetSystemset_system for the parameter 'border_shape_models'"border_shape_models""border_shape_models""border_shape_models""border_shape_models".

'use_clutter'"use_clutter""use_clutter""use_clutter""use_clutter"

Disables or enables the use of clutter parameters for the shape model ModelIDModelIDModelIDmodelIDmodel_id, which have been set previously using set_shape_model_clutterset_shape_model_clutterSetShapeModelClutterSetShapeModelClutterset_shape_model_clutter. The value of 'use_clutter'"use_clutter""use_clutter""use_clutter""use_clutter" can be 'true'"true""true""true""true" or 'false'"false""false""false""false". Note that the value of 'use_clutter'"use_clutter""use_clutter""use_clutter""use_clutter" affects the expected number of entries in the input parameter MinScoreMinScoreMinScoreminScoremin_score of the find operators. Please refer to the documentation of the different find operators, e.g., find_shape_modelfind_shape_modelFindShapeModelFindShapeModelfind_shape_model.

For newly created shape models, the use of clutter parameters is disabled. After calling set_shape_model_clutterset_shape_model_clutterSetShapeModelClutterSetShapeModelClutterset_shape_model_clutter, the use of clutter parameters is enabled. Clutter parameters and the value of 'use_clutter'"use_clutter""use_clutter""use_clutter""use_clutter" can be queried using get_shape_model_clutterget_shape_model_clutterGetShapeModelClutterGetShapeModelClutterget_shape_model_clutter.

'model_cache'"model_cache""model_cache""model_cache""model_cache"

Disables or enables the use of an internal cache based on temporary memory that is used by a shape model when it executes, e.g., find_shape_modelfind_shape_modelFindShapeModelFindShapeModelfind_shape_model. The size of the cache depends on whether the find operation needs a big search space with many discretization steps. This means that a small AngleStepAngleStepAngleStepangleStepangle_step and ScaleStepScaleStepScaleStepscaleStepscale_step and a big AngleExtentAngleExtentAngleExtentangleExtentangle_extent and a big range given by ScaleMinScaleMinScaleMinscaleMinscale_min and ScaleMaxScaleMaxScaleMaxscaleMaxscale_max result in a big memory consumption. Switching the 'model_cache' off (by setting 'false'"false""false""false""false") sometimes results in slightly longer execution times but constantly small memory footprint, particularly important in embedded applications. By default, this cache is switched on ('true'"true""true""true""true").

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:

• ModelIDModelIDModelIDmodelIDmodel_id

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Parameters

Result

If the parameters are valid, the operator set_shape_model_paramset_shape_model_paramSetShapeModelParamSetShapeModelParamset_shape_model_param returns the value 2 ( H_MSG_TRUE) . If necessary an exception is raised.
