Description

The operator create_local_deformable_modelcreate_local_deformable_modelCreateLocalDeformableModelCreateLocalDeformableModelCreateLocalDeformableModel prepares a template, which is passed in the image TemplateTemplateTemplateTemplatetemplate, as a deformable model used for local deformable matching. The ROI of the model is passed as the domain of TemplateTemplateTemplateTemplatetemplate.

The local deformable matching can be used to detect an object that is distorted by a local deformation. This is similar to create_planar_uncalib_deformable_modelcreate_planar_uncalib_deformable_modelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModel or create_planar_calib_deformable_modelcreate_planar_calib_deformable_modelCreatePlanarCalibDeformableModelCreatePlanarCalibDeformableModelCreatePlanarCalibDeformableModel which require that the object is rigid. Further, it is an alternative to the mode 'max_deformation' in find_shape_modelfind_shape_modelFindShapeModelFindShapeModelFindShapeModel. Here, the model remains rigid but is able to tolerate small deformations. In contrast to find_shape_modelfind_shape_modelFindShapeModelFindShapeModelFindShapeModel, create_local_deformable_modelcreate_local_deformable_modelCreateLocalDeformableModelCreateLocalDeformableModelCreateLocalDeformableModel can be used to estimate the deformation and rectify the image area where the object is found. Further, create_local_deformable_modelcreate_local_deformable_modelCreateLocalDeformableModelCreateLocalDeformableModelCreateLocalDeformableModel can cope with bigger deformations.

As described in create_planar_uncalib_deformable_modelcreate_planar_uncalib_deformable_modelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModel, the origin (reference point) of the model is defined as the center of gravity of the domain (region) of the model image TemplateTemplateTemplateTemplatetemplate. Further, the axis-aligned enclosing rectangle of the domain of the TemplateTemplateTemplateTemplatetemplate is used to determine the area of the search image that is rectified in calls of find_local_deformable_modelfind_local_deformable_modelFindLocalDeformableModelFindLocalDeformableModelFindLocalDeformableModel.

For further explanation on the parameters used for the creation of a local deformable model we refer to the description of create_planar_uncalib_deformable_modelcreate_planar_uncalib_deformable_modelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModel. Note, that the parameters of the actual deformation are set with the call of find_local_deformable_modelfind_local_deformable_modelFindLocalDeformableModelFindLocalDeformableModelFindLocalDeformableModel.

Execution Information
