Description

add_sample_identifier_training_dataadd_sample_identifier_training_dataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingData adds training data to an existing sample identifier. This is a prerequisite for the training of the sample identifier with the operator train_sample_identifiertrain_sample_identifierTrainSampleIdentifierTrainSampleIdentifierTrainSampleIdentifier.

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

In order to be able to identify objects, the SampleIdentifierSampleIdentifierSampleIdentifierSampleIdentifiersampleIdentifier must be trained with a representative set of sample images of the objects to be identified. These sample images must be added to the SampleIdentifierSampleIdentifierSampleIdentifierSampleIdentifiersampleIdentifier with add_sample_identifier_training_dataadd_sample_identifier_training_dataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingData.

With each call of add_sample_identifier_training_dataadd_sample_identifier_training_dataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingData, one SampleImageSampleImageSampleImageSampleImagesampleImage is added to the SampleIdentifierSampleIdentifierSampleIdentifierSampleIdentifiersampleIdentifier. The complete training data, which consists of all the sample images that have been added to the sample identifier with multiple calls of add_sample_identifier_training_dataadd_sample_identifier_training_dataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingData, must 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 trained to the background of the sample images.

Note that in contrast to the preparation data, it is essential that the requirements mentioned above are fulfilled. Otherwise, the sample identifier will not be able to identify the objects for which relevant sample images are missing.

Also 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_preparation_dataadd_sample_identifier_preparation_dataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationDataAddSampleIdentifierPreparationData and prepare_sample_identifierprepare_sample_identifierPrepareSampleIdentifierPrepareSampleIdentifierPrepareSampleIdentifier) are identical. 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_training_dataadd_sample_identifier_training_dataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingData. 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_training_dataadd_sample_identifier_training_dataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingDataAddSampleIdentifierTrainingData returns the object sample index of the training sample given in SampleImageSampleImageSampleImageSampleImagesampleImage. This index can, e.g., be used to remove this sample from the training data, if the sample identifier should be retrained based on a different set of training data.
