get_features_ocr_class_mlpT_get_features_ocr_class_mlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlp (Operator)

Name

get_features_ocr_class_mlpT_get_features_ocr_class_mlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlp — Compute the features of a character.

Signature

get_features_ocr_class_mlp(Character : : OCRHandle, Transform : Features)

Description

get_features_ocr_class_mlpget_features_ocr_class_mlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlp computes the features of the character given by CharacterCharacterCharacterCharactercharacter with the OCR classifier OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle and returns them in FeaturesFeaturesFeaturesFeaturesfeatures. In contrast to do_ocr_single_class_mlpdo_ocr_single_class_mlpDoOcrSingleClassMlpDoOcrSingleClassMlpDoOcrSingleClassMlp and do_ocr_multi_class_mlpdo_ocr_multi_class_mlpDoOcrMultiClassMlpDoOcrMultiClassMlpDoOcrMultiClassMlp, the character is passed as a single image object. Hence, before calling get_features_ocr_class_mlpget_features_ocr_class_mlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlp, reduce_domainreduce_domainReduceDomainReduceDomainReduceDomain must typically be called. The parameter TransformTransformTransformTransformtransform determines whether the feature transformation specified with Preprocessing in create_ocr_class_mlpcreate_ocr_class_mlpCreateOcrClassMlpCreateOcrClassMlpCreateOcrClassMlp for the classifier should be applied (TransformTransformTransformTransformtransform = 'true'"true""true""true""true") or whether the untransformed features should be returned (TransformTransformTransformTransformtransform = 'false'"false""false""false""false"). get_features_ocr_class_mlpget_features_ocr_class_mlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlp can be used to inspect the features that are used for the classification.

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

CharacterCharacterCharacterCharactercharacter (input_object) singlechannelimage → object (byte / uint2)

Input character.

OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle (input_control) ocr_mlp → (handle)

Handle of the OCR classifier.

TransformTransformTransformTransformtransform (input_control) string → (string)

Should the feature vector be transformed with the preprocessing?

Default value: 'true' "true" "true" "true" "true"

List of values: 'false'"false""false""false""false", 'true'"true""true""true""true"

FeaturesFeaturesFeaturesFeaturesfeatures (output_control) real-array → (real)

Feature vector of the character.

If the parameters are valid, the operator get_features_ocr_class_mlpget_features_ocr_class_mlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlpGetFeaturesOcrClassMlp returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
