 A connected picture frame displaying historic images
-===== Ideas / Iterations =====
+{{https://farm9.staticflickr.com/8681/16672996925_ec53c13c61.jpg}}
-  - Download the pictures to the Raspi and display one of them (warmup)
+===== Story =====
-  - 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:
+  * The Picture This "smart" frame shows police photographs of homeless people by Carl Durheim (1810-1890)
-  - Use the Raspi Cam to detect a visitor in front of the frame and stop the slideshow
+  * By looking at a picture, you trigger a face detection algorithm to analyse both, you and the homeless person
-  - Use the Raspi Cam to take a picture of the face of the visitor
+  * The algorithm detects gender, age and mood of the person on the portrait (not always right)
-  - Detect faces in the images [DONE, manually, using online service]
+  * You, as a spectator, become part of the system / algorithm judging the homeless person
-  - ...merge visitor and picture faces :-)
+  * 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 =====
-  * Picture frame, shows police photographs of the homeless by Carl Durheim (1810-1890)
   * Who were those people? Why were they homeless? What was their crime?
-  * Picture frame has a camera doing face detection, but does not reveal that
-  * Instead, a spectator looking at the frame triggers face detection on the portrait
-  * Face detection algorithm (in the cloud) detects gender, age and mood
-  * Spectator becomes the judge / part of the system / algorithm
-  * Person on the picture is at the mercy of the spectator, once again
   * How would we treat them? How will they / we be treated tomorrow? (by algorithms)
