A connected picture frame displaying historic images

The Picture This “smart” frame shows police photographs of homeless people by Carl Durheim (1810-1890)
By looking at a picture, you trigger a face detection algorithm to analyse both, you and the homeless person
The algorithm detects gender, age and mood of the person on the portrait (not always right)
You, as a spectator, become part of the system / algorithm judging the homeless person
The person on the picture is at the mercy of the spectator, once again

Who were those people? Why were they homeless? What was their crime?
How would we treat them? How will they / we be treated tomorrow? (by algorithms)

Download the pictures to the Raspi and display one of them (warmup)
Slideshow and turning the images 90° to adapt to the screensize
Play around with potentiometer and Arduino to bring an analog input onto the Raspi (which only has digital I/O)
Connect everything and adapt the slideshow speed with the potentiometer
Display the name (extracted from the filename) below the picture

next steps, more ideas:

Use the Raspi Cam to detect a visitor in front of the frame and stop the slideshow
Use the Raspi Cam to take a picture of the face of the visitor
Detect faces in the camera picture
Detect faces in the images [DONE, manually, using online service]
…merge visitor and picture faces
