Warning🔗

testd_ocr_class_boxTestdOcrClassBox is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM or CNN based operators instead.

Description🔗

The operator testd_ocr_class_boxTestdOcrClassBox 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 Charactercharactercharacter the corresponding name (class) ClassclassValclass must be specified. The gray values are passed in Imageimageimage. When the operator has finished the parameter Confidenceconfidenceconfidence provides information about how sure a character belongs to the (arbitrary chosen) class.

Execution information🔗

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🔗

Charactercharactercharacter (input_object) region(-array) → objectHObjectHRegionHObjectHobject

Characters to be tested.

Imageimageimage (input_object) singlechannelimage → object (byte / uint2)HObject (byte / uint2)HImage (byte / uint2)HObject (byte / uint2)Hobject (byte / uint2)

Gray values for the characters.

OcrHandleocrHandleocr_handle (input_control) ocr_box → (handle)HTuple (HHandle)HOCRBox, HTuple (IntPtr)HHandleHtuple (handle)

ID of the desired OCR-classifier.

ClassclassValclass (input_control) string(-array) → (string)HTuple (HString)HTuple (string)MaybeSequence[str]Htuple (char*)

Class (name) of the characters.

Default: 'a'"a"

Confidenceconfidenceconfidence (output_control) real(-array) → (real)HTuple (double)HTuple (double)Sequence[float]Htuple (double)

Confidence for the character to belong to the class.

Result🔗

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