Thanks a lot, shree. It seems you know everything. I tried the MICR0.traineddata and the first two mcr.traineddata. The last one was blocked by the browser. Each of the traineddata had mixed results. All of them are getting symbols fairly good but getting spaces randomly and reading some numbers wrong.
MICR0 seems the best among them. Did you suggest that you'd be able to update it? It gets tripple D very often where there's only one, and so on. Also, I tried to fine tune from MICR0 but I found that I need to change the language-specific.sh. It specifies some parameters for each language. Do you have any guidance for it? 2019年6月14日金曜日 1時48分40秒 UTC+9 shree: > > see > http://www.devscope.net/Content/ocrchecks.aspx > https://github.com/BigPino67/Tesseract-MICR-OCR > https://groups.google.com/d/msg/tesseract-ocr/obWI4cz8rXg/6l82hEySgOgJ > > On Mon, Jun 10, 2019 at 11:21 AM ElGato ElMago <[email protected] > <javascript:>> wrote: > >> That'll be nice if there's traineddata out there but I didn't find any. >> I see free fonts and commercial OCR software but not traineddata.
