OCR with tesseract under OpenBSD
|
|
================================
|
|
|
|
Here's a quick HOWTO about optical character recognition using:
|
|
scanimage(1) -- from the sane-backends package
|
|
unpaper -- from the unpaper package
|
|
convert(1) -- from the ImageMagick package
|
|
tesseract
|
|
|
|
$ scanimage --mode gray --resolution 300 > scan.pnm
|
|
$ unpaper -b 0.5 -w 0.8 -l single scan.pnm scan1.pnm
|
|
$ convert scan1.pnm scan.tif
|
|
$ tesseract scan.tif scan.txt
