Description

The operator get_shape_model_paramsget_shape_model_paramsGetShapeModelParamsGetShapeModelParamsGetShapeModelParams returns the parameters of the shape model ModelIDModelIDModelIDModelIDmodelID that were used to create it using create_shape_modelcreate_shape_modelCreateShapeModelCreateShapeModelCreateShapeModel, create_scaled_shape_modelcreate_scaled_shape_modelCreateScaledShapeModelCreateScaledShapeModelCreateScaledShapeModel, or create_aniso_shape_modelcreate_aniso_shape_modelCreateAnisoShapeModelCreateAnisoShapeModelCreateAnisoShapeModel. In particular, this output can be used to check the parameters NumLevelsNumLevelsNumLevelsNumLevelsnumLevels, AngleStepAngleStepAngleStepAngleStepangleStep, ScaleStepScaleStepScaleStepScaleStepscaleStep, and MinContrastMinContrastMinContrastMinContrastminContrast if they were determined automatically during the model creation with create_shape_modelcreate_shape_modelCreateShapeModelCreateShapeModelCreateShapeModel, create_scaled_shape_modelcreate_scaled_shape_modelCreateScaledShapeModelCreateScaledShapeModelCreateScaledShapeModel, or create_aniso_shape_modelcreate_aniso_shape_modelCreateAnisoShapeModelCreateAnisoShapeModelCreateAnisoShapeModel.

If the shape model was created using create_shape_modelcreate_shape_modelCreateShapeModelCreateShapeModelCreateShapeModel or create_scaled_shape_modelcreate_scaled_shape_modelCreateScaledShapeModelCreateScaledShapeModelCreateScaledShapeModel a single value is returned in ScaleMinScaleMinScaleMinScaleMinscaleMin, ScaleMaxScaleMaxScaleMaxScaleMaxscaleMax, and ScaleStepScaleStepScaleStepScaleStepscaleStep. This parameters corresponds to the isotropic scaling parameters of the shape model. If the shape model was created using create_aniso_shape_modelcreate_aniso_shape_modelCreateAnisoShapeModelCreateAnisoShapeModelCreateAnisoShapeModel two values each are returned in the above three parameters. Here, the first value of the respective parameter refers to the scaling in the row direction, while the second value refers to the scaling in the column direction.

Note that the parameters OptimizationOptimizationOptimizationOptimizationoptimization and ContrastContrastContrastContrastcontrast that also can be determined automatically during the model creation cannot be queried by using get_shape_model_paramsget_shape_model_paramsGetShapeModelParamsGetShapeModelParamsGetShapeModelParams. If their value is of interest determine_shape_model_paramsdetermine_shape_model_paramsDetermineShapeModelParamsDetermineShapeModelParamsDetermineShapeModelParams should be used instead.
