Conclusion

You can scan documents and extract text from them without much fuss with shell tools. The sample script provided here already gives a functional result. With a bit of shell know-how, you can expand upon this script and customize it to your taste, for example, with the Unpaper [7] tool, which is also available in the repositories.
