Description

add_sample_identifier_preparation_dataadd_sample_identifier_preparation_dataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationData adds preparation data to an existing sample identifier. This is a prerequisite for the preparation of the sample identifier with the operator prepare_sample_identifierprepare_sample_identifierPrepareSampleIdentifierPrepareSampleIdentifierPrepareSampleIdentifier.

For an explanation of the concept of sample-based identification see the introduction of chapter Identification / Sample-Based.

To achieve the maximum identification rate, the internal data structure of the sample identifier must be adapted to the objects to be identified. For this, it is useful to provide sample images of all kinds of objects to be identified.

With each call of add_sample_identifier_preparation_dataadd_sample_identifier_preparation_dataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationData, features of one SampleImageSampleImageSampleImageSampleImagesampleImage are added to the SampleIdentifierSampleIdentifierSampleIdentifierSampleIdentifiersampleIdentifier. The complete preparation data, which consists of all features of all sample images that have been added to the sample identifier with multiple calls of add_sample_identifier_preparation_dataadd_sample_identifier_preparation_dataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationData, should cover

The domain of the SampleImageSampleImageSampleImageSampleImagesampleImage should be reduced to the object, which is visible in the image. This is necessary to avoid that the SampleIdentifierSampleIdentifierSampleIdentifierSampleIdentifiersampleIdentifier is adapted to the background of the sample images.

If you cannot provide preparation data that fulfills all of the above mentioned requirements, the sample identifier may be prepared as well, but the identification rate may be slightly worse.

Note that you must provide RGB color images, if the generic parameter 'add_color_info'"add_color_info""add_color_info""add_color_info""add_color_info" has been set to 'true'"true""true""true""true" in create_sample_identifiercreate_sample_identifierCreateSampleIdentifierCreateSampleIdentifierCreateSampleIdentifier.

Ideally, the images used for preparation and training (see add_sample_identifier_training_dataadd_sample_identifier_training_dataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingData and train_sample_identifiertrain_sample_identifierTrainSampleIdentifierTrainSampleIdentifierTrainSampleIdentifier) are identical. This can easily be realized by reusing the preparation data for the training of the SampleIdentifierSampleIdentifierSampleIdentifierSampleIdentifiersampleIdentifier. To be able to reuse the preparation data, the index of the object must be given in ObjectIdxObjectIdxObjectIdxObjectIdxobjectIdx. Otherwise, the ObjectIdxObjectIdxObjectIdxObjectIdxobjectIdx can be set to 'unknown'"unknown""unknown""unknown""unknown". See prepare_sample_identifierprepare_sample_identifierPrepareSampleIdentifierPrepareSampleIdentifierPrepareSampleIdentifier for an explanation on how to reuse preparation data for the training of the sample identifier.

The following generic parameters can be used to influence the behavior of the operator add_sample_identifier_preparation_dataadd_sample_identifier_preparation_dataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationData. These parameters and their corresponding values can be specified by using GenParamNameGenParamNameGenParamNameGenParamNamegenParamName and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue, respectively. The following values for GenParamNameGenParamNameGenParamNameGenParamNamegenParamName are possible:

'image_resize_method'"image_resize_method""image_resize_method""image_resize_method""image_resize_method":

See create_sample_identifiercreate_sample_identifierCreateSampleIdentifierCreateSampleIdentifierCreateSampleIdentifier for a description of this parameter.

List of values: 'none'"none""none""none""none", 'scale_factor'"scale_factor""scale_factor""scale_factor""scale_factor", 'subsampling_step'"subsampling_step""subsampling_step""subsampling_step""subsampling_step", 'image_area'"image_area""image_area""image_area""image_area"

Default value: If the 'image_resize_method'"image_resize_method""image_resize_method""image_resize_method""image_resize_method" is not set explicitly by this operator, the value that has been set with create_sample_identifiercreate_sample_identifierCreateSampleIdentifierCreateSampleIdentifierCreateSampleIdentifier or set_sample_identifier_paramset_sample_identifier_paramSetSampleIdentifierParamSetSampleIdentifierParamSetSampleIdentifierParam will be used.

'image_resize_value'"image_resize_value""image_resize_value""image_resize_value""image_resize_value":

See create_sample_identifiercreate_sample_identifierCreateSampleIdentifierCreateSampleIdentifierCreateSampleIdentifier for a description of this parameter.

Suggested values: 0.25, 0.5, 1.0, 2, 3, 4

Default value: If the 'image_resize_value'"image_resize_value""image_resize_value""image_resize_value""image_resize_value" is not set explicitly by this operator, the value that has been set with create_sample_identifiercreate_sample_identifierCreateSampleIdentifierCreateSampleIdentifierCreateSampleIdentifier or set_sample_identifier_paramset_sample_identifier_paramSetSampleIdentifierParamSetSampleIdentifierParamSetSampleIdentifierParam will be used.

add_sample_identifier_preparation_dataadd_sample_identifier_preparation_dataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationData returns the object sample index of the preparation sample given in SampleImageSampleImageSampleImageSampleImagesampleImage. This index can, e.g., be used to remove this sample from the preparation data, if the sample identifier should be prepared based on a different set of preparation data.
