===== Picture This =====

A connected picture frame displaying historic images

===== Story =====

  * 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

===== How it works =====

  * Picture frame has a camera doing face detection for presence detection
  * Pictures have been pre-processed using a cloud service
  * Detection is still rather slow (should run faster on the Raspi 2)
  * Here's a little video https://www.flickr.com/photos/tamberg/16053255113/

===== Questions (not) answered =====

  * 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)

===== Ideas / Iterations =====
  - 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 :-)

Not used this time, but might be useful 
  * https://thinkrpi.wordpress.com/2013/05/22/opencv-and-camera-board-csi/ - old Raspian versions did not have the latest OpenCV installed. Nice howto for that
  * https://realpython.com/blog/python/face-recognition-with-python/ - OpenCV, nice but not used
  * http://docs.opencv.org - not used directly, only via SimpleCV
