Start by running in debug mode and tell us at what line the code is actually crashing. I cannot read memory locations myself, but I am guessing it cannot read in your image!

that exception was generated by createfilter .. I am getting this error : OpenCV Error: Bad argument (Default classifier file not found!) in cv::text::ERClassifierNM1::ERClassifierNM1, file C:\opencv_ex\opencv_contrib-master\modules\text\src\erfilter.cpp,

It is simply, somewhere you are reading in a model, probably by a relative path. The error states clearly that it is not able to read the file. So please try absolute paths.

If they are there then download them and link them to your sample!

Make sure that the path to load the model is the exact location where you saved it!
