Short Description
Installs Ocrad 0.26 in an Ubuntu based container.
Full Description


Docker container image for Ocrad based on Ubuntu. Will install Ocrad in the container.

For best results the characters should be at least 20 pixels high. If
they are smaller, try the --scale option. Scanning the image at 300 dpi
usually produces a character size good enough for ocrad.
Merged, very bold or very light (broken) characters are normally not
recognized correctly. Try to avoid them.

Usage: ocrad [options] [files]
