Description

The operator testd_ocr_class_boxtestd_ocr_class_boxtestd_ocr_class_boxTestdOcrClassBoxTestdOcrClassBox tests the confidence with which a character belongs to a given class. Any number of regions of an image can be passed. For each character (region) in CharacterCharacterCharacterCharactercharacter the corresponding name (class) ClassClassClassClassclassVal must be specified. The gray values are passed in ImageImageImageImageimage. When the operator has finished the parameter ConfidenceConfidenceConfidenceConfidenceconfidence provides information about how sure a character belongs to the (arbitrary chosen) class.

Parameters

CharacterCharacterCharacterCharactercharacter (input_object)  region(-array) → objectHRegionHRegionHRegionXHobject

Characters to be tested.

ImageImageImageImageimage (input_object)  image → objectHImageHImageHImageXHobject (byte / uint2)

Gray values for the characters.

ID of the desired OCR-classifier.

ClassClassClassClassclassVal (input_control)  string(-array) → HTupleHTupleVARIANTHtuple (string) (string) (char*) (BSTR) (char*)

Result

If the parameters are correct, the operator testd_ocr_class_boxtestd_ocr_class_boxtestd_ocr_class_boxTestdOcrClassBoxTestdOcrClassBox returns the value 2 (H_MSG_TRUE). Otherwise an exception will be raised.
