ARGUMENTSfilename
FUNCTIONtext_loadOCRHMMClassifierCNN
RETURN TYPEtext_OCRHMMDecoder_ClassifierCallback | null
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

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

deprecated: use loadOCRHMMClassifier instead

text_loadOCRHMMClassifierCNN(filename: EmbindString): text_OCRHMMDecoder_ClassifierCallback | null;
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.

Returns

The text_OCRHMMDecoder_ClassifierCallback | null result.
