Problem with OcrTesseract class. [closed]

edit

Hello everyone,

I hope you are all well. I have installed opencv with extra modules with help of this [https://putuyuwono.wordpress.com/2015...] tutorial. During configuration stage I have a message which says "Tesseract: NO"

After installation I have created a simple scene text detection project. And I have succesfully detected text in images.

After this part, I have tried to run ocr with below code.

// img1 is a CV_8UC3 typed mat image. and output is a string variable.

Ptr<OCRTesseract> ocr = OCRTesseract::create();
ocr->run(img1, output);

This piece of code runs without any error but does not give me any ocr result. I have tried different images but result is the same.

I have also tried to set parameters for create function.

Ptr<OCRTesseract> ocr = OCRTesseract::create("C:\\Program Files (x86)\\Tesseract-OCR\\tessdata", "eng", "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ");

Unfortunatelly this did not went well too. I did not get any errors but did not get a result too.

How can I make my code work?

Thanks in advance.

Here is full log generated after I hit configure button in CMAKE.
