I think, you are right... I upgraded to autoconf 2.69. And process moved a bit. But still when I am executing ./configure --enable-debug I got an error which says configure: error: Your compiler does not have the necessary c++11 support! Cannot proceed. Thus, looking into it.

[tesseract-ocr] tesseract does not recognize grey colored fonts in the images..
If we have a text not black, but light greyish. tesseract does not recognize it. Any solutions to this problem. Have attached images of the sample bill. Suppose I want to extract Base Fare Base Fare - *Rs 500* But Since Base Fare is light greyish. Tesseract does not recognize it at all. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
