I would like to be able to recognize character in a image. For that I try to use the sample code give here but I have this error. Any ideas ? thanks !

Ptr<OCRHMMDecoder::ClassifierCallback> ocr = loadOCRHMMClassifierCNN("OCRBeamSearch_CNN_model_data.xml.gz");

I have this error

OpenCV Error: Bad argument (Default classifier data file not found!) in OCRHMMClassifierCNN, file /home/benng/bin/opencv_working_dir/opencv_contrib/modules/text/src/ocr_hmm_decoder.cpp, line 973

this file has to be in the folder, where you run the program.
