RE: [tesseract-ocr] Re: Preprocess Image

[Art Rhyno .]

Maybe try a Gaussian blur and upsize a bit? Something like:

convert -blur 2x10 -resize 110%

Hi:
When trying to OCR the above image, the date 09/02/2017 is always wrong, 
(0G/02/2017).



This is tesseract 4 running on linux, the cmd line is:

tesseract stdin stdout -l eng --psm 11 --oem 1 -c textonly_pdf=1 -c 
tessedit_create_pdf=1 | pdftotext -layout - -



Is there any way to pre-process the image to make it work? (preferably using 
convert)



Thanks

Hongguo An
