Picture This

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

• 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/

• 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)

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

next steps, more ideas:

1. Use the Raspi Cam to detect a visitor in front of the frame and stop the slideshow
2. Use the Raspi Cam to take a picture of the face of the visitor
3. Detect faces in the camera picture
4. Detect faces in the images [DONE, manually, using online service]
5. …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
• http://makezine.com/projects/pi-face-treasure-box/ - maybe a nice weekend project
