Detailed Description

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.

virtual void cv::text::OCRBeamSearchDecoder::ClassifierCallback::eval	(	InputArray	image,
		std::vector< std::vector< double > > &	recognition_probabilities,
		std::vector< int > &	oversegmentation
	)

virtual

The character classifier must return a (ranked list of) class(es) id('s)

Parameters

image	Input image CV_8UC1 or CV_8UC3 with a single letter.
recognition_probabilities	For each of the N characters found the classifier returns a list with class probabilities for each class.
oversegmentation	The classifier returns a list of N+1 character locations' x-coordinates, including 0 as start-sequence location.
