How to cleanup an image before OCR ?
Posted: Thu May 23, 2013 4:40 pm
Hello,
I'm trying to do OCR with the image i've attached and the result is "25755" instead "421,22" (300dpi, converted to 1bpp, OCRTesseractSetPassCount=5, OCRTesseractSetOCRContext=0 Document , CharWhiteList="0123456789.,-" )
I know the problem is the "noise" at the upper area, how can i erase this "noise" ?
I've seen the demo "document clean up.exe", and i've tried to solve it with "Removelines","RemoveBlob","FxBitonalDespeckleMore" methods unsuccessful.
Regards!!
