testd_ocr_class_box(Character, Image : : OcrHandle, Class : Confidence)

描述

The operator testd_ocr_class_boxtestd_ocr_class_boxTestdOcrClassBoxTestdOcrClassBoxTestdOcrClassBoxtestd_ocr_class_box 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 CharacterCharacterCharacterCharactercharactercharacter the corresponding name (class) ClassClassClassClassclassValclass must be specified. The gray values are passed in ImageImageImageImageimageimage. When the operator has finished the parameter ConfidenceConfidenceConfidenceConfidenceconfidenceconfidence provides information about how sure a character belongs to the (arbitrary chosen) class.
