Hope to generate OCR results

Suggested Fix:

Is there a lack of dependency? Or how can I run correctly to get OCR results?
Thank you！

What is the output from tesseract -v on the machines where it is not working?

[jingkanghou]

The output is as follows:

C:\Program Files (x86)\Tesseract-OCR>tesseract -v

Please try running Tesseract with parameter -c dotproduct=sse.

Thank you very much for your reply. There will be no error in the running process.
However, OCR results still have some problems. The test process is as follows:

My Name is houji
My Name is houji
My Name is houji

• Test 1：

tesseract c:\t\wz123.jpg c:\t\wz.txt -c dotproduct=sse

Results：

• Test 2(use tessdata_best--eng.traineddata)：

tesseract c:\t\wz123.jpg c:\t\wz.txt -c dotproduct=sse

Results：

• Test3(use tessdata_fast--chi_sim.traineddata)：

tesseract -l chi_sim c:\t\wz123.jpg c:\t\wz.txt -c dotproduct=sse

Whether it is possible to further optimize by setting parameters to achieve appropriate results by using tessdata_fast--chi_sim.traineddata, thank you!

[jingkanghou]

I saw the '-c dotproduct=' instruction information from tesseract-ocr#2098 today, the problem has been solved, thank you!
