Dependency on External Tools

ImageMagick (package graphicsmagick-imagemagick-compat),
dcmtk,
parallel,
tesseract-ocr,
and Local Adaptive Binarization.

Install Debian packages

First, install Debian packages by a single command:

$ apt install dcmtk graphicsmagick-imagemagick-compat parallel tesseract-ocr

Image Binarization tool

It is used Christian Wolf's Local Adaptive Binarization method for image binarization.

You can download, compile and install Local Adaptive Binarization from https://github.com/vcelakp/local_adaptive_binarization.

$ git clone https://github.com/vcelakp/local_adaptive_binarization
$ cd local_adaptive_binarization/
$ make
$ sudo cp binarizewolfjolion /usr/local/bin/

For success source code compilation, it is necessary to have already installed OpenCV4 libraries:

libopencv-calib3d
libopencv-core
libopencv-imgcodecs
libopencv-imgproc
libopencv-contrib
libopencv-stitching
libopencv-superres
libopencv-videostab
