Function opencv::text::load_ocr_beam_search_classifier_cnn

pub fn load_ocr_beam_search_classifier_cnn(
    filename: &str
) -> Result<Ptr<OCRBeamSearchDecoder_ClassifierCallback>>

Allow to implicitly load the default character classifier when creating an OCRBeamSearchDecoder object.

Parameters

• filename: The XML or YAML file with the classifier model (e.g. OCRBeamSearch_CNN_model_data.xml.gz)

The CNN default classifier is based in the scene text recognition method proposed by Adam Coates & Andrew NG in [Coates11a]. The character classifier consists in a Single Layer Convolutional Neural Network and a linear classifier. It is applied to the input image in a sliding window fashion, providing a set of recognitions at each window location.
