Hello everyone,
I hope you are all well. I have installed opencv with extra modules with help of this [https://putuyuwono.wordpress.com/2015/04/23/building-and-installing-opencv-3-0-on-windows-7-64-bit/] 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 of after CMAKE configuration.
