Install ImageMagick for image conversion:
brew install imagemagick
Install tesseract for OCR:
brew install tesseract --all-languages
Or install without --all-languages
and install them manually as needed.
Make sure the input image is a grayscale .tif
and fairly large. ~500x150 was too small, while ~2000*500 worked very well.
convert input.png -resize 400% -type Grayscale input.tif
OCR it. The default language is English. Language codes are 3 chars per man tesseract
.
tesseract -l eng input.tif output
This creates output.txt
.
Is there a
brew
route for getting & running the latest version of tesseract (LSTM-based,4.0.0
)?I'm currently using:
..on macOS, High Sierra 10.13.4 17E202 x86_64. Thanks!
