get_shape_model_contoursget_shape_model_contoursGetShapeModelContoursGetShapeModelContours (Operator)

Name

get_shape_model_contoursget_shape_model_contoursGetShapeModelContoursGetShapeModelContours — Return the contour representation of a shape model.

Signature

get_shape_model_contours( : ModelContours : ModelID, Level : )

The operator get_shape_model_contoursget_shape_model_contoursGetShapeModelContoursGetShapeModelContoursGetShapeModelContours returns a representation of the shape model ModelIDModelIDModelIDModelIDmodelID as XLD contours in ModelContoursModelContoursModelContoursModelContoursmodelContours. The parameter LevelLevelLevelLevellevel determines for which pyramid level of the model the contour representation should be returned. The contours can be used, for example, to visualize the found instances of the model in an image. It should be noted that the position of ModelContoursModelContoursModelContoursModelContoursmodelContours is normalized such that the reference point of the model (see set_shape_model_originset_shape_model_originSetShapeModelOriginSetShapeModelOriginSetShapeModelOrigin) lies at the pixel position (0,0). Hence, the contours simply need to be translated to the found position in the image (and possibly rotated and scaled around this point).

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters

ModelContoursModelContoursModelContoursModelContoursmodelContours (output_object) xld_cont-array → object

Contour representation of the shape model.

ModelIDModelIDModelIDModelIDmodelID (input_control) shape_model → (integer)

Handle of the model.

LevelLevelLevelLevellevel (input_control) integer → (integer)

Pyramid level for which the contour representation should be returned.

Default value: 1

Suggested values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Restriction: Level >= 1

Result

If the handle of the model is valid, the operator get_shape_model_contoursget_shape_model_contoursGetShapeModelContoursGetShapeModelContoursGetShapeModelContours returns the value 2 (H_MSG_TRUE). If necessary an exception is raised.
