OCR of Chicago 1909 Renumbering Plan

Requirements:

• Python 3 (probably at least 3.4)
• pipenv (pip3 install pipenv)
• tesseract (brew install tesseract, at least if you have a mac and homebrew working)
• imagemagick / ghostscript

Using this repository:

The working/ subfolders contain a folder for each page. Each contains a page.png file that's the baseline page. It'll attempt to auto-deskew and crop each page. If you want to manually override this process, create a page-handcrop.png file in the working directory. Some already have them.

pipenv install

make all at the top level should attempt to deskew, crop, split, and OCR everything, building CSV output in each working dir.

pipenv shell

make setup

make all

After that, concatenating all the page.csv files in each working dir should work.

csvstack working/*/page.csv > all_data.csv
