Struct opencv::text::OCRHMMDecoder_ClassifierCallback

pub struct OCRHMMDecoder_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 loadOCRHMMClassifierNM and KNN model provided in https://github.com/opencv/opencv_contrib/blob/master/modules/text/samples/OCRHMM_knn_model_data.xml.gz.
