Struct opencv::text::OCRBeamSearchDecoder_ClassifierCallback

pub struct OCRBeamSearchDecoder_ClassifierCallback { /* fields omitted */ }

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 loadOCRBeamSearchClassifierCNN with all its parameters provided in https://github.com/opencv/opencv_contrib/blob/master/modules/text/samples/OCRBeamSearch_CNN_model_data.xml.gz.
