Collection of OCR-related python tools and wrappers from the OCR-D team

Installation

To bootstrap the tool, you’ll need installed (Ubuntu packages):

• Python (python)
• pip (python-pip)

To install system-wide:

make deps-ubuntu deps install

To develop, install to a virtualenv

pip install virtualenv
virtualenv --no-site-packages venv

Usage

pyocrd installs a binary ocrd that can be used to invoke the processors directly (ocrd process) or start (development) webservices (ocrd server)

TODO: Update docs here.

Examples:

# List available processors
ocrd process

# Region-segment with tesserocr all files in METS INPUT fileGrp
ocrd process -m /path/to/mets.xml segment-region/tesserocr

# Chain multiple processors
ocrd process -m /path/to/mets.xml characterize/exif segment-line/tesserocr recognize/tesserocr

# Start a processor web service at port 6543
ocrd server process -p 6543
http PUT localhost:6543/characterize url==http://server/path/to/mets.xml
