textclassOpenCV 5.0.0

ARGUMENTSConstructor or factory
CLASStext_OCRHMMDecoder_ClassifierCallback
RETURN TYPEOwned native handle
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Native object: release it with using or delete(). Factories can return null; check before calling methods.

Callback with the character classifier is made a class.

This way it hides the feature extractor and the classifier itself, so developers can write
their own OCR code.

The default character classifier and feature extractor can be loaded using the utility function
loadOCRHMMClassifierNM and KNN model provided in
<https://github.com/opencv/opencv_contrib/blob/master/modules/text/samples/OCRHMM_knn_model_data.xml.gz>.
