Unraphael

Unraphael is a digital workflow tool that uses computer vision to unravel the artistic practice of Raphael (Raffaello Sanzio, 1483-1520), while providing new digital approaches for the study of artistic practice in art history. Dozens of faithful reproductions survive of Raphael's paintings, attesting to the lucrative practice of serial production of paintings within the artist's workshop and to the lasting demand for the master's designs.

Unraphael provides a flexible and easy-to-use GUI to inspect and assess the structural similarity of figure-outlines in images. Photographs of paintings are used as input for the application.

While Unraphael was made for art historians and researchers in the humanities to study the artistic practices of and the process of making copies of paintings, the functionality of Unraphael extends well beyond the study of Raphael's paintings and can be used for a wide range of applications in the digital humanities and beyond.

Systemd service

To run unraphael as a service, you can create a systemd service file. This will allow you to start, stop, and restart unraphael using systemd. 1. Create a service file for unraphael, for example `/etc/systemd/system/unraphael.service`:

[Unit]
Description=Unraphael dashboard
After=network.target

[Service]
Environment="XDG_CACHE_HOME=/cache/dir" HOME="/writable/dir"
User=youruser
WorkingDirectory=/home/youruser
ExecStart=/home/youruser/.local/bin/unraphael-dash
Restart=on-failure
User=youruser
WorkingDirectory=/home/youruser
ExecStart=/home/youruser/.local/bin/unraphael-dash
Restart=on-failure

[Install]
WantedBy=multi-user.target

Replace `/cache/dir` and `/writable/dir` with the actual paths to your cache and writable directories. Replace `youruser` with your actual username. Also, make sure that the path to `unraphael-dash` is correct. You can find the correct path using `which unraphael-dash`. 2. Enable the service:

sudo systemctl enable unraphael.service

3. Start the service:

sudo systemctl start unraphael.service

4. Check the status of the service:

sudo systemctl status unraphael.service

5. To stop the service:

sudo systemctl stop unraphael.service
