描述

set_planar_uncalib_deformable_model_metricset_planar_uncalib_deformable_model_metricSetPlanarUncalibDeformableModelMetricSetPlanarUncalibDeformableModelMetricSetPlanarUncalibDeformableModelMetricset_planar_uncalib_deformable_model_metric changes the value of the parameter MetricMetricMetricMetricmetricmetric that was selected during the creation of the deformable model ModelIDModelIDModelIDModelIDmodelIDmodel_id from XLD contours. Because no information about the polarity of the model contours is available for XLD contours, the polarity is determined based on a representative ImageImageImageImageimageimage. For this, the model contours are mapped to the respective position where the object appears in the ImageImageImageImageimageimage using HomMat2DHomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d, which can be obtained by a previous call to find_planar_uncalib_deformable_modelfind_planar_uncalib_deformable_modelFindPlanarUncalibDeformableModelFindPlanarUncalibDeformableModelFindPlanarUncalibDeformableModelfind_planar_uncalib_deformable_model.

The parameter MetricMetricMetricMetricmetricmetric then determines the conditions under which the model is recognized later in the search image. If MetricMetricMetricMetricmetricmetric = 'use_polarity'"use_polarity""use_polarity""use_polarity""use_polarity""use_polarity", the object in the image and the model must have the same contrast. If, e.g., the model is a bright object on a dark background, the object is found only if it is also brighter than the background. If MetricMetricMetricMetricmetricmetric = 'ignore_global_polarity'"ignore_global_polarity""ignore_global_polarity""ignore_global_polarity""ignore_global_polarity""ignore_global_polarity", the object is found in the image also if the contrast reverses globally. In the above example, the object hence is also found if it is darker than the background. The runtime of find_planar_uncalib_deformable_modelfind_planar_uncalib_deformable_modelFindPlanarUncalibDeformableModelFindPlanarUncalibDeformableModelFindPlanarUncalibDeformableModelfind_planar_uncalib_deformable_model will increase slightly in this case.

It must be ensured that the object contours in the ImageImageImageImageimageimage have the same (or inverse) polarity as the object contours in the image in which the object must be searched later. Especially, the object must not be occluded in the ImageImageImageImageimageimage and the background must be either brighter than the object or darker. Otherwise, the determined polarity of the model contour will not represent the polarity of the object contour during the search. Note that only the polarity of the contours is determined, not their contrast. Note also that the polarity is determined from a single-channel image, only. If a multi-channel image is passed in ImageImageImageImageimageimage, only the first channel will be used (and no error message will be returned).

A typical proceeding is to read the XLD contours from file. Since these XLD contours do not provide polarity information, the model must be created from the XLD contours by setting the parameter MetricMetricMetricMetricmetricmetric to 'ignore_local_polarity'"ignore_local_polarity""ignore_local_polarity""ignore_local_polarity""ignore_local_polarity""ignore_local_polarity". Then, in a first search image the model is recognized. The transformation that maps the model contours to the position of the object in the search image (HomMat2DHomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d) can be determined from the matching result. To verify the match interactively, the model contours can be mapped to this position. If the matching result is correct, the value of the parameter MetricMetricMetricMetricmetricmetric can be changed, e.g., to 'use_polarity'"use_polarity""use_polarity""use_polarity""use_polarity""use_polarity". This leads to a faster and more robust recognition in the following images.
