set_shape_model_paramT_set_shape_model_paramSetShapeModelParamSetShapeModelParamset_shape_model_param (Operator)
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_paramSetShapeModelParamSetShapeModelParamSetShapeModelParamset_shape_model_param sets the selected parameters
GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name in the shape model ModelIDModelIDModelIDModelIDmodelIDmodel_id. The following
parameters can be modified:
'min_contrast'"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 ModelIDModelIDModelIDModelIDmodelIDmodel_id.
Thereby, the value of 'min_contrast'"min_contrast""min_contrast""min_contrast""min_contrast""min_contrast" that was originally set,
e.g., with create_shape_modelcreate_shape_modelCreateShapeModelCreateShapeModelCreateShapeModelcreate_shape_model, is overwritten for the shape model
ModelIDModelIDModelIDModelIDmodelIDmodel_id. Note that if the shape model ModelIDModelIDModelIDModelIDmodelIDmodel_id was read from
file and if this file should be changed as well, the shape model
ModelIDModelIDModelIDModelIDmodelIDmodel_id must again be written to file after the execution of the
operator set_shape_model_paramset_shape_model_paramSetShapeModelParamSetShapeModelParamSetShapeModelParamset_shape_model_param.
'timeout'"timeout""timeout""timeout""timeout""timeout"
Sets the maximum runtime of the operators used to find the shape model
ModelIDModelIDModelIDModelIDmodelIDmodel_id (e.g., find_shape_modelfind_shape_modelFindShapeModelFindShapeModelFindShapeModelfind_shape_model). This is especially useful
in cases where a maximum cycle time has to be ensured. The 'timeout'"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""timer_mode" set via set_systemset_systemSetSystemSetSystemSetSystemset_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""false".
'border_shape_models'"border_shape_models""border_shape_models""border_shape_models""border_shape_models""border_shape_models"
This parameter determines whether the shape model ModelIDModelIDModelIDModelIDmodelIDmodel_id to be
found with, e.g., find_shape_modelfind_shape_modelFindShapeModelFindShapeModelFindShapeModelfind_shape_model, may lie partially outside the
image (i.e., whether they may cross the image border).
The value of 'border_shape_models'"border_shape_models""border_shape_models""border_shape_models""border_shape_models""border_shape_models" can be 'true'"true""true""true""true""true",
'false'"false""false""false""false""false", or 'system'"system""system""system""system""system". The value 'system'"system""system""system""system""system"
is the default behavior and uses the system-wide used value that was set by
set_systemset_systemSetSystemSetSystemSetSystemset_system for the parameter 'border_shape_models'"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""use_clutter"
Disables or enables the use of clutter parameters for the shape model
ModelIDModelIDModelIDModelIDmodelIDmodel_id, which have been set previously using
set_shape_model_clutterset_shape_model_clutterSetShapeModelClutterSetShapeModelClutterSetShapeModelClutterset_shape_model_clutter. The value of 'use_clutter'"use_clutter""use_clutter""use_clutter""use_clutter""use_clutter" can be
'true'"true""true""true""true""true" or 'false'"false""false""false""false""false". Note that the value of
'use_clutter'"use_clutter""use_clutter""use_clutter""use_clutter""use_clutter" affects the expected number of entries in the input
parameter MinScoreMinScoreMinScoreMinScoreminScoremin_score of the find operators. Please refer to the
documentation of the different find operators, e.g., find_shape_modelfind_shape_modelFindShapeModelFindShapeModelFindShapeModelfind_shape_model.
For newly created shape models, the use of clutter parameters is disabled.
After calling set_shape_model_clutterset_shape_model_clutterSetShapeModelClutterSetShapeModelClutterSetShapeModelClutterset_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""use_clutter" can be
queried using get_shape_model_clutterget_shape_model_clutterGetShapeModelClutterGetShapeModelClutterGetShapeModelClutterget_shape_model_clutter.
'model_cache'"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_modelFindShapeModelFindShapeModelFindShapeModelfind_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 AngleStepAngleStepAngleStepAngleStepangleStepangle_step and
ScaleStepScaleStepScaleStepScaleStepscaleStepscale_step and a big AngleExtentAngleExtentAngleExtentAngleExtentangleExtentangle_extent and a big range given by
ScaleMinScaleMinScaleMinScaleMinscaleMinscale_min and ScaleMaxScaleMaxScaleMaxScaleMaxscaleMaxscale_max result in a
big memory consumption. Switching the 'model_cache' off (by setting 'false'"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""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:
During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

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