Description
The operator testd_ocr_class_boxtestd_ocr_class_boxTestdOcrClassBoxTestdOcrClassBoxTestdOcrClassBox 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.
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) region(-array) → objectHRegionHRegionHobject
Characters to be tested.
ImageImageImageImageimage (input_object) singlechannelimage → objectHImageHImageHobject (byte / uint2)
Gray values for the characters.
OcrHandleOcrHandleOcrHandleOcrHandleocrHandle (input_control) ocr_box → HOCRBox, HTupleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
ID of the desired OCR-classifier.
ClassClassClassClassclassVal (input_control) string(-array) → HTupleHTupleHtuple (string) (string) (HString) (char*)
Class (name) of the characters.
Default value:
'a'
"a"
"a"
"a"
"a"
ConfidenceConfidenceConfidenceConfidenceconfidence (output_control) real(-array) → HTupleHTupleHtuple (real) (double) (double) (double)
Confidence for the character to belong to the class.
Result
If the parameters are correct, the operator
testd_ocr_class_boxtestd_ocr_class_boxTestdOcrClassBoxTestdOcrClassBoxTestdOcrClassBox returns the value 2 (H_MSG_TRUE).
Otherwise an exception will be raised.
